Use 1 Used as solvent and moisturizing agent, also used to make plasticizer, medicine, polyester resin, polyurethane resin, etc. Use 2 Used as chromatographic analysis reagent, also used in organic synthesis. Use 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. Use 4 solvent. Wetting agent. Intermediates of plasticizers. Crosslinking agent for the manufacture of polyurethane elastomers. Organic Synthesis. Manufacture of tetrahIdrofuran.
