1, 4-butanediol is widely used. In the United States and Western Europe more than half of the production of tetrahydrofuran, followed by the production of γ -butyrolactone 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.
The esters from 1, 4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylate and polyester.
1, 4-butanediol has good moisture absorption and flexibility, can be used as gelatin softener and water absorbent, cellophane and other non-paper treatment agent. N-methyl pyrrolidone, n-vinyl pyrrolidone and other pyrrolidone derivatives can also be prepared, but also used in the preparation of vitamin B6, pesticides, herbicides and a variety of processes of solvents, plasticizers, lubricants, humidifiers, softness, adhesives and electroplating industry brighteners.
