Acetic acid, the simplest organic acid, is one of the most commonly used raw materials in organic chemical industry
It is mainly used to prepare organic reagents such as acetic anhydride, vinyl acetate, acetate, metal acetate, chloroacetic acid, cellulose acetate, etc. it is used in industry to produce ethyl acetate, edible spices, wine spices, vinylon, etc. it can also be used as acid washing solution in electroplating.
As the simplest organic acid, acetic acid is the final product of many biological metabolism. Therefore, compared with other chemical products, acetic acid can not only be produced by various chemical synthesis methods, but also be obtained by biological fermentation. Compared with industrial synthesis, although the output of this method only accounts for 10% of the total output, many countries stipulate that vinegar for food use must come from biological fermentation, and the process of producing acetic acid by fermentation has also been further developed in recent years.
