Acetic aci CAS 64-19-7

Acetic acid is a bulk chemical product and is one of the most important organic acids. It is mainly used in the production of vinyl acetate, acetic anhydride, acetate esters and cellulose acetate. Polyvinyl acetate can be used to prepare films and adhesives, and is also the raw material for the synthetic fibre vinylon. Cellulose acetate can be used to make rayon and cinema film. Acetic acid esters are excellent solvents and are widely used in the paint industry. Acetic acid can also be used to synthesise acetic anhydride, diethyl malonate, ethyl acetoacetate, haloacetic acid, etc. It can also be used to manufacture drugs such as aspirin, and can be used to produce acetate salts. It is widely used in pesticides, pharmaceuticals and dyestuffs, in the manufacture of photographic drugs, in fabric printing and dyeing and in the rubber industry.

In the food industry, acetic acid is used as an acidifying agent, flavour enhancer and spice. In the manufacture of vinegar, acetic acid is diluted with water to a concentration of 4-5% and various flavouring agents are added to obtain edible vinegar. As an acidifier, it is used in appropriate dilution and can be used to mix beverages and canned food, such as making tomatoes, asparagus, baby food, sardines, squid and other canned food, making soft drinks, cold drinks, candy, baked goods, pudding type, gum medium sugar, condiments and so on.

Acetic acid has a preservative effect. 1.5% has a significant antibacterial effect. Within the range of 3%, it can avoid the green and black colour of the meat caused by mould spots.
