Usage
1, 4-butanediol is widely used. In the United States and Western Europe for more than half of the production of tetrahydrofuran, followed by the production of γ-butanolactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastics; 1, 4-butanediol is used as a chain extender and polyester raw material for the production of polyurethane elastomers and soft polyurethane foam plastics; Esters of 1, 4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylates and polyesters. 1, 4-butanediol has good hygroscopic flexibility, can be used as gelatin softener and water absorbent, cellophane and other non-paper treatment agent. Can also be prepared N-methylpyrrolidone, N-vinyl pyrrolidone and other pyrrolidone derivatives, also used in the preparation of vitamin B6, pesticides, herbicides and a variety of process solvents, plasticizers, lubricants, humidifiers, softness, adhesives and electroplating industry brightener.
1. 1, 4-butanediol mainly has three industrial chains.
(1) Tetrahydrofuran production, accounting for about 60% of the consumption of 1, 4-butanediol, tetrahydrofuran through ring-opening polymerization to produce poly (PTMEG), pharmaceutical intermediates or directly used as solvents;
(2) production of γ-butanediol, about 20% of the consumption of 1, 4-butanediol, γ-butanediol and acetylene production of 2-pyrrolidone, vinyl pyrrolidone and polyethylene pyrrolidone;
(3) the production of PBT resin for home appliance industry, color TV industry; About 9% of the consumption of 1, 4-butanediol. The production of 1, 4-butanediol has been greatly increased and it has become an important basic organic chemical product.
2. Main application fields of 1, 4-butanediol.
(1) As a solvent, it can be used in medicine, fragrance and chemical industries;
(2) As a chemical raw material, can produce polytetramethyleneglycol PTMEG, tetrahydrothiophene, pyronolane ketone, 2, 3-dichlorotetrahydrofuran, 1, 4-dichloroethane, butylene lipid, pentose lipid, ink and flavor, etc.
(3) Production of polyether, polyurethane ultra-soft elastic fiber and high elastic rubber is the best material.
