#acetic acid

[rye-in-a-coat]

I was quick to smell my thumb, my right thumb (I asked the woman with the special ink if it had to be the left or right one; she said any would work); and a repugnant and strong smell of acetic acid filled my inner flesh tubes which made me let out a quite audible disgust reflex.

I had just voted in my first election for this nation; and after that my family and I went to the mall. Despite how many mentioned was the fact that so many stores would give free stuff after you showed them your inked thumb; I went to none of them, I wasn't really excited for such.

I wasn't excited for voting in the first place. Me like many people have lost all their faith in the whole process, I had planned since the last year that I would straight up cast an invalid/blank vote, and the whole campaign process that came after just reassured me on such choice.

So if I was going to do that, at least I should make something out of it.

And that's how the name of "Boxa Caken Funfetti" written with the black crayon that is given at the voting place, marked the first ever recorded case of a Sparklecare character being voted as a candidate in a presidential election.

Vinegar could be secret ingredient in fight against climate crisis

Chemical engineers at Monash University have developed an industrial process to produce acetic acid that uses the excess carbon dioxide (CO2) in the atmosphere and has a potential to create negative carbon emissions.

Acetic acid is an important chemical used in several industrial processes and is an ingredient in household vinegar, vinyl paints and some glues. Worldwide industrial demand for acetic acid is estimated to be 6.5 million tons per year.

This world-first research, published in Nature Communications, shows that acetic acid can be made from captured CO2 using an economical solid catalyst to replace the liquid rhodium or iridium based catalysts currently used.

Liquid catalysts require additional separation and purification processes. Using a solid catalyst made from a production method that doesn't require further processing also reduces emissions.

Geographically, the acetic acid market demonstrates regional price variations based on production capacity, local demand, and raw material availability. China, for example, holds a dominant position in global acetic acid production and demand. China's influence on prices is profound because it not only consumes a large percentage of the global output but also exports extensively, setting a pricing tone for the global market. Any change in China's manufacturing policies, environmental regulations, or demand trends for downstream products can significantly affect the global price trajectory. In recent years, China's environmental crackdown on high-pollution factories led to plant closures and capacity reductions, tightening the supply and subsequently driving prices up.

Seasonality plays a role in pricing, as demand for acetic acid varies across different sectors. In the textiles industry, demand tends to peak during specific periods of high garment production, leading to a spike in acetic acid requirements for dye manufacturing. Similarly, the production of paints and coatings is affected by construction activity, which often fluctuates with weather patterns, economic cycles, and infrastructure investments. Economic recessions typically lead to reduced demand for durable goods and building projects, suppressing acetic acid consumption and prices, while economic booms stimulate demand across key industries, leading to price increases.

Over the past few years, price volatility has also been influenced by supply chain disruptions and trade policies. The COVID-19 pandemic notably disrupted global logistics and supply routes, causing shortages and delivery delays of chemical commodities, including acetic acid. This led to price spikes in several regions, particularly where local production was insufficient to meet demand. As markets stabilized post-pandemic, prices gradually adjusted; however, the long-term impact on global trade flows continues to reshape market behaviors. Additionally, geopolitical tensions, such as trade wars and sanctions, can alter export-import dynamics, affecting the availability and pricing of acetic acid in global markets.

The sustainability trend sweeping across the chemical industry is reshaping the landscape for acetic acid production. With increasing consumer and regulatory pressure for greener products, companies are exploring bio-based methods of producing acetic acid, focusing on reducing the environmental impact. While these initiatives show promise, they also involve higher initial production costs, which can lead to price increases during the early adoption phases. Over time, as technologies mature and scale economies are realized, more stable and potentially cost-effective solutions may emerge, potentially leveling out prices or offering price reductions.

Demand for derivatives, such as vinyl acetate monomer (VAM), remains a significant driver for acetic acid pricing. As one of the primary end-uses, VAM is used extensively in adhesives, coatings, and films. When demand for VAM surges, acetic acid prices often follow suit due to increased production needs. Conversely, any downturn in industries that heavily use VAM can create a surplus of acetic acid, leading to price softening. Monitoring downstream markets thus becomes critical for anticipating future price movements.

In North America and Europe, regulatory changes related to environmental safety and emissions standards may impact the operational costs of acetic acid plants. Stringent regulations could necessitate upgrades to plant facilities and operational modifications, potentially resulting in higher production costs and, by extension, higher acetic acid prices. Conversely, favorable trade policies or incentives for sustainable practices may provide cost relief and increase global competitiveness, thereby influencing price behavior.

Overall, acetic acid prices are subject to a complex interplay of global supply-demand dynamics, raw material costs, energy market influences, trade policies, sustainability initiatives, and regional market trends. For industry participants, remaining vigilant to these multifaceted factors is key to navigating pricing fluctuations and planning for cost-effective sourcing strategies. As the chemical industry continues to evolve with shifting regulatory landscapes and technological advancements, the market for acetic acid will undoubtedly undergo further transformations, necessitating adaptive strategies and continual market monitoring to optimize purchasing decisions and maintain competitiveness.

From Vinegar to Versatility: Unveiling Acetic Acid's Production Journey and Multifaceted Applications

Vinegar. That pantry staple we splash on salads and fries. But did you know this common household item packs a surprising scientific punch? The key ingredient in vinegar is Acetic Acid, a clear, colorless liquid with a powerful odor that's sure to clear your sinuses. Acetic Acid is much more than just a souring agent. It's a workhorse in the chemical world, playing a crucial role in the production of countless everyday items. From the plastics in your water bottle to the medicines in your cabinet, Acetic Acid might be lurking behind the scenes.

In this blog, we'll delve deeper into the fascinating world of Acetic Acid. We'll explore its surprising range of uses, from the industrial to the culinary, and uncover the science behind its unique properties. So, whether you're a curious cook or a science enthusiast, get ready to learn a whole new side to the humble vinegar you know and love!

Introduction

Acetic Acid, a clear organic compound with a strong odor and tart flavor, is industrially synthesized through methanol carbonylation or ethylene oxidation. Methanol carbonylation is the preferred method over ethylene oxidation. Key technology providers for Acetic Acid production include British Petroleum, Celanese, Eastman's acetyls technology, and LyondellBasell. Similar to ethanol, Acetic Acid is a water-friendly solvent, readily mixing with water, chloroform, and hexane, and dissolving substances such as oils, sulfur, and iodine.

It serves as a chemical precursor for various compounds like acetic anhydride, esters, vinyl acetate monomer (VAM), and various polymers. Acetic Acid is also utilized in vinegar production, where it constitutes 5 percent of the solution, finding applications in the food and beverage industry for marinades, pickling solutions, and salad dressings. Additionally, vinegar, containing Acetic Acid, can be added during food preparation to minimize contamination in meat and poultry products.

Manufacturing Process

Acetic Acid primarily undergoes production through chemical methods, utilizing both homogeneous and heterogeneous catalytic processes. The predominant method involves the carbonylation of methanol, a process initially established by Monsanto, which has since progressed into the Cavita process. This evolved approach offers flexibility in catalyst selection and incorporates advancements in process intensification techniques.

Methanol carbonylation process:

• The carbonylation process, commonly referred to as the Monsanto process, stands as the predominant commercial method for synthesizing Acetic Acid.

• Methanol and carbon monoxide undergo a liquid-phase reaction under the influence of a rhodium (Rh)-based catalyst at temperatures ranging between 150 to 200 degrees Celsius and pressures between 30 to 50 bar, yielding Acetic Acid with a selectivity of around 95% and minor side products including formic acid and formaldehyde.

• In this process, hydrogen iodide serves as an alkali promoter, with the reaction occurring in the liquid phase and methyl acetate acting as a solvent using a homogeneous catalyst. The controlled introduction of water is necessary for the reaction, which is generated in situ through the reaction of methanol with hydrogen iodide.

• The reaction rate in the Monsanto process is directly influenced by the concentration of water. Byproducts such as CO2, H2, and methanol are generated during the reaction, with the produced methanol being recycled. Over time, the process has undergone evolution, with various strategies implemented to separate pure Acetic Acid from a mixture of water and byproducts. BP Chemicals modified this process by substituting the rhodium-based catalyst with an Iridium (Ir) catalyst, resulting in what is known as the Cavita process.

• The selection of Ir as a coordination metal presents a relatively more economical approach compared to rhodium. The use of an iridium catalyst enhances the overall reaction rate.

The following chemical reaction represents the same:

Acetaldehyde oxidation process

• The acetaldehyde oxidation method was one of the largely used method used for synthesizing Acetic Acid. Initially, acetaldehyde was prepared through the oxidation of ethylene, employing palladium and copper chloride catalysts, after which it underwent further oxidation to yield Acetic Acid.

• Alternatively, a similar procedure utilizing cobalt and chromium-based catalysts has been documented, operating at a pressure of 55 bar and a temperature of 150 degrees Celsius. Another variant of this process involves a one-step conversion of ethylene to Acetic Acid, employing lead and lead-platinum based catalysts at elevated pressures, in contrast to the acetaldehyde oxidation method, albeit with lower Acetic Acid yields.

Hydrocarbon oxidation process

• Petroleum-derived hydrocarbons, including butane and naphtha, serve as the primary sources for producing Acetic Acid, a crucial chemical compound, through a reaction catalyzed by cobalt acetate and chromium acetate.

• This chemical transformation unfolds within a relatively elevated temperature range of 150-230°C and under pressures ranging from 50 to 60 bar. The utilization of petroleum feedstock, comprising a diverse hydrocarbon blend, initiates a multifaceted reaction pathway leading to the synthesis of not only Acetic Acid but also a spectrum of byproducts, notably acetone, formic acid, and propionic acid, alongside the target compound. Consequently, the resultant Acetic Acid may not exhibit a high degree of purity due to the coexistence of these impurities.

• However, this process's strength lies in its capability to generate a mixture of volatile fatty acids, rendering it more suitable for applications necessitating such a blend. Therefore, while it may not yield pristine Acetic Acid, this method finds relevance in industrial contexts where a mixture of volatile fatty acids is desirable. This underscores the importance of understanding the nuanced outcomes of chemical processes and tailoring them to meet specific industrial requirements.

Acetic Acid serves as a vital chemical reagent in the synthesis of various compounds. Its primary application lies in the production of vinyl acetate monomer, followed closely by acetic anhydride and ester production. While Acetic Acid is commonly associated with vinegar, its usage volume in this context is relatively minor compared to its extensive utilization in industrial processes for the production of essential chemical compounds. Acetic Acid serves as a foundational component in the production of various chemicals, including vinyl acetate, acetic anhydride, and acetate esters. Vinyl acetate is utilized in the synthesis of polyvinyl acetate, a versatile polymer applied in paints, adhesives, plastics, and textile finishes. Acetic anhydride finds application in the manufacturing of cellulose acetate fibers and plastics used in photographic film, clothing, and coatings. Furthermore, Acetic Acid plays a crucial role in the chemical process to produce purified terephthalic acid (PTA), essential for manufacturing PET plastic resin. PET resin is extensively employed in synthetic fibers, food containers, beverage bottles, and plastic films.
