| APPLICATION | ||||
| 1, 4-butanediol is widely used. More than half are used in the production of tetrahydrofuran in the United States and Western Europe, followed by γ-butylactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastics; 1, 4-butanediol is used as chain extender and polyester raw material to produce polyurethane elastomers and soft polyurethane foams. 1, 4-butanediol esters are good Chemicalbook plasticizers for cellulose, polyvinyl chloride, polyacrylates and polyesters. 1, 4-butanediol has a good hygroscopic flexibility, can be used as gelatin softener and absorbent, cellophane and other non-paper primer. It can also prepare N-methylpyrrolidone, n-vinylpyrrolidone and other pyrrolidone derivatives. It is also used in the preparation of vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softeners, adhesives and brighteners for the electroplating industry. | ||||
| Methods of production | |||
| 1. Acetylene process is prepared by the reaction of acetylene and formaldehyde in the presence of Cu-Bi catalyst at 98kPa, 80-95℃ to produce 1, 4-butynediol. The latter was then hydrogenated to 1, 4-butenediate at 1.372-2.06MPa, 50-60℃ with skeleton nickel catalyst, followed by Ni-Cu-Mn/Al2O3 catalytic hydrogenation (13.7-20.6MPa, 120-140℃) to 1, 4-butenedichemicalbook alcohol. Metal ions are removed by ion exchange resin, and then purified by distillation. 2. Maleic anhydride hydrogenation process 3. Butadiene process from 1, 3-butadiene and acetic acid and oxygen through the acetyl oxidation reaction, to produce 1, 4-diacetoxy-2-butadiene, and then through hydrogenation, hydrolysis. 4.1, 4-dichloroprene method 1, 4-dichloroprene is an intermediate product of the process of butadiene production of chlorobutadiene, using it as raw material, through hydrolysis, hydrogenation to obtain 1, 4-butadiol. | |||
