It is used as chromatographic analysis reagent and also for organic synthesis. 1,4-butanediol is widely used. In the United States and Western Europe, more than half are used to produce tetrahydrofuran, followed by production γ- Butyrolactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastic; 1,4-butanediol is used as chain extender and polyester raw material to produce polyurethane elastomer and soft polyurethane foam; Esters prepared from 1,4-butanediol are good plasticizers for cellulose, PVC, polyacrylate and polyester. 1,4-butanediol has good hygroscopicity and flexibility, and can be used as gelatin softener and water absorbent, and as a treatment agent for cellophane and other unused paper. It can also be used to prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, as well as to prepare vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softness, adhesives and brighteners for electroplating industry. Reagent for chemical analysis, used as stationary liquid for gas chromatography. It is used as solvent, non-toxic antifreeze, food emulsifier, hygroscopic agent, and organic synthesis. Pharmaceutical and food industries. Solvent. Wetting agent. Intermediate of plasticizer. Crosslinking agent for manufacturing polyurethane elastomer. Organic synthesis. Manufacture tetrahydrofuran.
