1,4-Butanediol

1, 4-butanediol is a colorless, viscous liquid that reacts with strong oxidants. It is an important basic organic chemical raw material, mainly used in the production of polydibutyl terephthalate (PBT), polyurethane, gamma-butyrolactone and tetrahydrofuran

It is used as an analytical reagent for chromatography and also for organic synthesis. 1, 4-butanediol is widely used. In the United States and Western Europe, more than half of it is used in the production of tetrahydrofuran, followed by the production of γ-butyrolactone and polybutylene terephthalate, which is a rapidly developing engineering plastic; 1, 4-butanediol is used as chain extender and polyester raw material in the production of polyurethane elastomers and soft polyurethane foams. The esters obtained from 1, 4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylate and polyester. 1, 4-butanediol has good hygroscopic flexibility and can be used as a gelatin softener and water absorbent, as a treatment agent for cellophane and other non-paper. N-methylpyrrolidone, n-vinylpyrrolidone and other pyrrolidone derivatives are also used in the preparation of vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softeners, adhesives and brighteners for the electroplating industry. Reagent for chemical analysis, used as a stationary liquid for gas chromatography. Used as solvent, non-toxic antifreeze agent, food emulsifier, hygroscopic agent, for organic synthesis. Pharmaceutical, food industry. The solvent. Wetting agent. Intermediate of plasticizer. A crosslinking agent for the manufacture of polyurethane elastomers. Organic synthesis. To make tetrahydrofuran
