1,4-Butanediol

Packaging and Shipping Aluminum foil bag, cartons, plastic contain,drums or as required; By Express, by Air, by Sea according to the Amount. Usage "Purpose 1 As a solvent and humidifier, also used in plasticizer, medicine, polyester resin, polyurethane resin, etc Purpose 2 As a chromatographic analysis reagent, also used in organic synthesis Purpose 3 1, 4-butanediol is widely used. In the United States and Western Europe more than half is used for the production of tetrahydrofuran, followed by γ -butyralactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastics; 1, 4-butanediol is used as chain extender and raw material of polyester to produce polyurethane elastomer and soft polyurethane foam. The ester from 1, 4-butanediol is a good plasticizer for cellulose, polyvinyl chloride, polyacrylate and polyester. 1, 4-butanediol has a good hygroscopic flexibility, can be used as gelatin softener and water absorbent, cellophane and other non-paper treatment agent. Also can prepare n-methyl pyrrolidone, n-vinyl pyrrolidone and other pyrrolidone derivatives, also used in the preparation of vitamin B6, pesticides, herbicides and the role of a variety of process solvents, plasticizers, lubricants, humidifiers, softness, adhesives and plating industry brightener. Purpose 4 Solvents. Wetting agents. Plasticizer intermediate. Cross-linking agent for the manufacture of polyurethane hyperprojectiles. Organic synthesis. Making tetrahydrofuran."
