Transparent Liquid 1 4 BD Chemical Intermediates For GBL THF And PBT

Chemical Intermediates 1,4-Butanediol BDO For GBL, THF And PBT

1, 4-butanediol (BDO) is an important organic and fine chemical raw material, which is widely used in medicine, chemical industry, textile, paper making, automobile and daily chemical industry, etc. BDO can produce tetrahydrofuran (THF), polybutanediol terephthalate (PBT), γ-butanediol (GBL), polyurethane Resin (PU Resin), coatings and plasticizers, and as a solvent and brightening agent in the electroplating industry.

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.
