1.4-Butanediol (C4H10O2)

1.4-Butanediol has a wide range of uses. For the production of gamma-butyrolactone and polybutylene terephthalate, the latter being a rapidly developing engineering plastic. 1.4-butanediol is used as a chain extender and polyester raw material for the production of polyurethane elastomers and flexible polyurethane foam.

The esters made from 1.4-butanediol are good plasticizers for cellulose and polyesters. 1.4-Butanediol has good hygroscopic flexibility and can be used as gelatin softener and treatment agent for cellophane and other unused paper.

BDO can also prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, also used in the preparation of vitamin B6, pesticides, herbicides and the role of a variety of process solvents, lubricants, humidifiers, softness, adhesives and intermediates in the electroplating industry brightener, solvent, wetting agent, plasticizer.

Manufacturing polyurethane high elasticity of cross-linking agent, organic synthesis. BDO can prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, also used in the preparation of vitamin B6, pesticides, herbicides.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.

1.4-Butanediol ( BDO ) is used industrially as a solvent and in the manufacture of certain types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.
