The main purpose of acetic acid are: (1) vinyl acetate is the largest consumer in the field of vinyl acetate preparation, accounting for over 44% acetic acid consumption, which is widely used in the production of polyvinyl alcohol, polyvinyl alcohol, vinyl copolymer resin adhesive. , paint, etc. (2) a solvent. acetic acid is used as a solvent in many industrial chemical reactions. (3) cellulose acetate. ?????? acetate can be used for making acetic acid, acetic anhydride of 80% for the manufacture of cellulose acetate , and the rest for medicine, perfumes, dyes, etc. (4) acetate. ethyl acetate, butyl acetate, acetic acid are two important downstream products. acetate used in varnishes, diluting materials, leather, nitrocellulose, plastic, dyes, drugs and spices; butyl acetate is a good organic solvent for nitrocellulose, paints, inks, leather, pharmaceuticals, plastics and perfumes, and other fields of ethanol oxidation by the ethanol in the presence of a catalyst and. oxygen oxidation reaction. C2H5OH + O2 = CH3COOH + H2O acetaldehyde oxidation Monsanto law before commercial production, most of the acetic acid is obtained from acetaldehyde oxidation. Although not be compared with the carbonylation methylation, the role of glacial acetic acid, this method is still the second industrial production of acetic acid. 2CH3CHO + O2 → 2CH3COOH acetaldehyde by oxidation of butane or light naphtha is, it can be generated through the hydration of ethylene. When butane or light naphtha is heated in air, and a variety of metal ions include magnesium, cobalt, chromium, and catalytic peroxide ions will decompose acetic acid. Chemical equation is as follows: 2 C4H10 + 5 O2 → 4 CH3COOH + 2 H2O This reaction can be carried out in the holding of liquid butane to make the maximum temperature and pressure, acetic acid agents, general reaction conditions are 150 ℃ and 55atm. Byproducts including butanone, ethyl acetate, formic acid and propionic acid. Because some byproducts also have economic value, it is possible to adjust the reaction conditions so that the byproducts generated more, but increase the cost of making the separation of acetic acid and reaction byproducts. Under similar conditions, the catalyst, Qibin District Hebi City glacial acetic acid, acetaldehyde can be oxidized by oxygen in the air to produce acetic acid: 2 CH3CHO + O2 → 2 CH3COOH also be oxidized copper hydroxide suspension: 2Cu (OH ) 2 + CH3CHO → CH3COOH + Cu2O ↓ + 2H2O use the new catalyst, the reaction can be obtained acetic acid yield more than 95%. The main by-products are ethyl acetate, formic acid and formaldehyde. Because of the relatively low-boiling byproducts of acetic acid, so it is easily removed by distillation.
