| wholesale Basic Organic Chemistry Production Method Product Name：1,4-Butanediol CAS. No.110-63-4 Molecular formula：C4H10O2 Application 1) 1,4 butanediol is an important organic chemical and fine chemical raw material, which is the basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fiber; PBT plastics is one of the five most promising engineering plastics. 2) 4-butanediol is the main raw material for the production of tetrahydrofuran, which is an important organic solvent. The polymerized polytetramethylene glycol ether (PTMEG) is the basic raw material for the production of highly elastic spandex (lycra fiber). Spandex is mainly used in the production of high - grade sportswear, swimwear and other high - elastic knitwear. 3) γ-butanolide is the downstream product of 1,4 butanediol, is the raw material for the production of 2-pyrrolidone and n-methylpyrrolidone products. From this, a series of high value-added products, such as vinylpyrrolidone and polyvinylpyrrolidone, are widely used in pesticide, medicine, cosmetics and other fields.

The acetylene method with acetylene and formaldehyde in the presence of Cu - Bi catalyst, made in 98 kpa, 80-95 ℃ reaction acetylene 1, 4 - butyl glycol. The latter then through skeleton nickel catalyst, from 1.372 to 2.06 MPa, 50 to 60 ℃ hydrogenation of 1, 4 - butylene acid salt, followed by Ni - Cu - Mn / Al2O3 further catalytic hydrogenation (13.7 20.6 MPa, 120-140 ℃) into 1, 4 - butanediol, after ion exchange resin to remove metal ions, then through distillation purification is tasted. 2. Maleic anhydride hydrogenation 4.1, 4-dichloroprene method 1, 4-dichloroprene is the intermediate product in the process of butadiene production of chloroprene.wholesale Basic Organic Chemistry website:http://www.eastchemy.com/basic-organic-chemistry/ |
