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.

On the other hand, the growing focus on sustainability has also led to innovations in acetic acid production processes, with some companies seeking to develop more energy-efficient or environmentally friendly methods. These advancements may help mitigate cost pressures in the long term.

Technological advancements and process improvements in acetic acid production have also played a role in shaping price trends. Over the years, significant efforts have been made to improve the efficiency of acetic acid production, reduce energy consumption, and lower production costs. For instance, advancements in catalysts and reaction systems have allowed for the more efficient conversion of methanol to acetic acid, reducing the amount of energy required and increasing overall yield. These innovations can help to keep acetic acid prices more stable, particularly when raw material prices are volatile. Additionally, the development of new production methods, such as the use of renewable feedstocks, may provide an opportunity to reduce the reliance on fossil fuels, potentially lowering production costs in the future.

The acetic acid market is also influenced by the global economic environment. When the global economy experiences growth, industrial production typically rises, leading to increased demand for acetic acid and its derivatives. For example, during periods of economic expansion, demand for consumer goods, automotive products, and construction materials tends to increase, driving up the need for acetic acid in the production of plastics, paints, and coatings. However, during economic downturns or periods of recession, industrial activity slows, and demand for acetic acid often declines, leading to downward pressure on prices.

In addition to economic factors, geopolitical issues can also impact acetic acid prices. Trade disputes, tariffs, and political instability in key producing or consuming regions can disrupt the supply chain, leading to price fluctuations. For instance, a trade dispute between major acetic acid-producing countries could lead to supply shortages or disruptions, causing prices to rise. Similarly, political instability in key regions, such as the Middle East, can affect the global supply of oil and natural gas, which are key feedstocks for methanol production, thereby impacting the cost of acetic acid.

The competitive landscape in the acetic acid market also affects pricing trends. The market is characterized by the presence of several large multinational chemical companies, as well as smaller regional producers. Intense competition among producers can sometimes lead to price wars, where companies reduce prices to gain market share. However, in times of supply shortages or rising raw material costs, producers may raise prices to offset the increased costs of production. Pricing strategies vary across regions, and producers often adjust their pricing based on local market conditions, production capacities, and demand fluctuations.

In conclusion, the acetic acid market is a complex and multifaceted industry that is influenced by a range of factors, including raw material prices, supply and demand dynamics, environmental regulations, and technological advancements. Price fluctuations in acetic acid are inevitable due to the interconnected nature of the global economy and supply chains. While the industry is expected to continue experiencing price volatility, ongoing innovations in production processes and the adoption of more sustainable practices may help stabilize prices over time. Understanding these factors and monitoring market trends is essential for businesses and consumers to navigate the ever-changing landscape of acetic acid pricing.

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.
