110-63-4 1 4 Butanediol BDO Pharmaceutical Raw Materials For General Reagents Alcohols

Pharmaceutical Materials 1,4-Butanediol BDO For General Reagents, Alcohols

1, 4-butanediol is an important organic chemical product, which is the main raw material of fine chemical products with high added value and synthetic leather. It is mainly used in the production of polybutanediol terephthalate (PBT), γ-butanolactone (GBL), polyurethane (PU), tetrahydrofuran (ton HF), COPEs, polymethyl ethylene glycol, N-methyl pyrrolidone (NMP), polyvinyl pyrrolidone and so on. In addition, it is also used in the synthesis of vitamin B6, pesticides, herbicides and solvents, humidifiers, plasticizers, pharmaceutical intermediates, chain growth agents and adhesives.

Purpose:

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.
