Miscible with water. Soluble in methanol, ethanol and acetone, slightly soluble in ether.Uses Used as solvents and humidifiers, but also used to make plasticizers, drugs, polyester resins, polyurethane resins, etc.Used as a reagent for chromatographic analysis, and also used in organic synthesisUses 1,4-butanediol is widely used. In the United States and Western Europe, more than half are used to produce tetrahydrofuran, followed by γ-butyrolactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastic; 1,4-butanediol is used as a Chain agents and polyester raw materials are used to produce polyurethane elastomers and flexible polyurethane foams; the esters made from 1,4-butanediol are good additives for cellulose, polyvinyl chloride, polyacrylates, and polyesters. Plasticizer. 1,4-butanediol has good hygroscopicity and flexibility, and can be used as gelatin softener and water absorbent, cellophane and other untreated paper. It can also prepare N-methylpyrrolidone, N-vinylpyrrolidone, and other pyrrolidone derivatives. It is also used to prepare vitamin B6, pesticides, herbicides, and solvents, plasticizers, lubricants, and humidifiers that act in various processes , Softness, adhesives and brighteners for the electroplating industry.Uses Chemical analysis reagents, used as gas chromatography fixed solution. Used as solvent, non-toxic antifreeze, food emulsifier, hygroscopic agent, used in organic synthesis. Pharmaceutical and food industry.Uses Solvent. Wetting agent. Plasticizer intermediate. Crosslinker for the manufacture of polyurethane elastomers. Organic Synthesis. Manufacture of tetrahydrofuran.Production method 1. The acetylene method firstly uses 1, acetylene and formaldehyde in the presence of a Cu-Bi catalyst to react at 98 kPa and 80-95 ° C to produce 1,4-butynediol. The latter is then catalyzed by framework nickel and hydrogenated to 1,4-butenedioate at 1.372-2.06 MPa at 50-60 ° C, followed by Ni-Cu-Mn / Al2O3 for further catalytic hydrogenation (13.7-20.6 MPa). (120-140 ºC) into 1,4-butanediol. After removing metal ions by ion exchange resin, it is purified by distillation to obtain pure product. 2. Maleic anhydride hydrogenation method 3. Butadiene method The acetyl oxidation reaction of 1,3-butadiene, acetic acid and oxygen to generate 1,4-diacetoxy-2-butene, and then hydrogenation, Made by hydrolysis. 4.1,4-Dichlorobutene method 1,4-Dichlorobutene is an intermediate product in the production of chloroprene from butadiene. It is used as a raw material to obtain 1,4-butanediol through hydrolysis and hydrogenation. .Category Flammable liquidToxicity classificationAcute toxicity Oral-rat LD50: 1525 mg / kg; Oral-mouse LD50: 2062 mg / kgFlammability and Hazardous Characteristics When exposed to heat, open flames are flammable; combustion produces irritating smokeStorage and transportation characteristics: storeroom is ventilated, low temperature and dry; stored separately from oxidantsFire extinguishing agent, dry powder, foam, water
