How is acetic acid made? Understand the process of acetic acid production

acetic acid is an crucial chemical raw material, broadly applied in food, medicine, plastics, textiles, dyes and other industries. In manufacturing production, there are two main methods to the preparation of acetic acid: the traditional acetic acid fermentation method and the modern synthesis method. We will examine these two preparation methods in detail to help you better understand the whole process of acetic acid production.

1. Acetic acid fermentation production method

Acetic acid fermentation is the earliest method to the preparation of acetic acid, usually using acetic acid bacteria to fermentation. And This method is mostly applied to small-scale production and mainly relies on the oxidative decomposition of organic matter. In general, the fermentation process will consumption alcohol containing raw materials, such as glucose, corn syrup and so on. During the fermentation process, acetic acid bacteria (such as bacteria of the genus Acetobacter) convert the alcohol in the raw material to acetic acid. The interaction is a biocatalytic process involving the supply of oxygen and the physiological processes of bacteria. By appropriately controlling the temperature, pH value and atmosphere flow, the fermentation of acetic acid bacteria is able to be carried out under the best conditions. But while the cost of fermentation is low, its production efficiency is low and it takes a long time to complete. But Therefore, this method is mainly applied in small-scale production, especially in some small factories or domestic acetic acid production. And

2. I've found that Acetic acid synthesis method

Compared with the traditional fermentation method, the synthetic method is greater applied to create acetic acid in modern sector. There are usually two methods to the synthesis of acetic acid: the coalification method and the methene method. In my experience,

2. 1 coalification method

The coalification method is a methodology that produces syngas (mainly CO and H2) through coal gasification, and then obtains acetic acid through catalytic interaction. You know what I mean?. This method is mainly applied in some extensive vegetation to form acetic acid by reacting synthesis gaseous with a catalyst under high temperature and high pressure conditions. The interaction of the process is:

[

CO H2O longrightarrow CH3COOH

]

this method has high production efficiency, is able to create acetic acid on a substantial scale, and has relatively little demand to raw materials. But

2. 2 Methene Method

The methene method is a method of obtaining acetic acid by reacting methene with carbon monoxide. And Based on my observations, The advantage of this method is that it's able to be carried out at a reduced interaction temperature and pressure, the interaction efficiency is high, and the by-product is less. This method is mainly applied in the petrochemical sector. Methylene method usually uses palladium catalyst to carry out the interaction, the basic steps of the interaction include the interaction of methylene and carbon monoxide to create acetic acid, and then through separation and treatment to obtain high purity acetic acid. I've found that

3. Generally speaking Acetic acid modern production advantage

Modern acetic acid production methods (especially the methene method) have signifiis able tot advantages over traditional fermentation methods. They enable high yields, short production cycles, and high product purity. And Due to their catalytic efficiency and optimization of interaction conditions, these synthesis methods greatly minimize production costs. Therefore, the current production of acetic acid is basically a synthetic method, especially extensive manufacturing production. And

4. But From what I've seen, Acetic acid production of environmental impact

while the synthesis method of acetic acid is greater efficient, its manufacturing process often involves high temperature and high pressure conditions, and will create some exhaust emissions and discarded materials aquatic environments. Therefore, modern acetic acid production vegetation need to strictly manage releases to minimize environmental impact. to instance, in coalification production, it's necessary to recover or minimize carbon dioxide releases to meet ecological preservation standards. Furthermore Modern acetic acid manufacturing process has greatly improved the efficiency and ecological preservation through technological improvement, however it'still necessary to take certain ecological preservation measures in the manufacturing process to ensure sustainable research. But summary: acetic acid is how to make?

The production methods of acetic acid mainly include traditional fermentation method and modern synthesis method. And Fermentation is suitable to small-scale production, while synthetic methods, such as coalification and methene, are suitable to extensive manufacturing production. With the progress of science and methodology, modern synthesis methods have gradually have become the mainstream, and have the advantages of high efficiency, low cost and high purity. With the improvement of ecological preservation standards, the future acetic acid production methodology might pay greater attention to ecological preservation and sustainable research.
