Application:

1.Used as solvent and moisturizing agent, also used to make plasticizer, medicine, polyester resin, polyurethane resin, etc.
2.Used as chromatographic analysis reagent, also used in organic synthesis.
3.BD is widely used. In the United States and Western Europe, more than half is used for the production of tetrahIdrofuran, followed by the production of γ-butIrolactone and polybutylene terephthalate, which are rapidly developing engineering plastics; BD is used as an additive Chain agents and polyester raw materials are used in the production of polyurethane elastomers and flexible polyurethane foams; esters made from BD are good additives for cellulose, polyvinyl chloride, polyacrylates and polyesters. plasticizer. BD has good hygroscopicity and flexibility, and can be used as gelatin softener and water-absorbing agent, as a treatment agent for cellophane and other unused paper. It can also prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, and also used to prepare vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, moisturizing agents for various processes , softness, adhesives and brighteners for the electroplating industry.
4.solvent. Wetting agent. Intermediates of plasticizers. Crosslinking agent for the manufacture of polyurethane elastomers. Organic Synthesis. Manufacture of tetrahIdrofuran.
