CAS No 110-63-4 1 4 Butanediol BDO Transparent Liquid With Purity 99.9%

CAS No 110-63-4 1,4-Butanediol BDO With Purity 99.9%

1,4-Butanediol is used in industrial area as a solvent, and as raw materials of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, In the presence of phosphoric acid and high temperature. It dehydrates to the important solvent tetrahydrofuran. At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form butyrolactone.

Useage

1,4 Butanediol is an important organic chemical and fine chemical raw material, and is the basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fibers; PBT plastics are the five most promising One of the engineering plastics.

1,4-Butanediol is the main raw material for the production of tetrahydrofuran, which is an important organic solvent. The polytetramethylene glycol PTMEG obtained after polymerization is the basic raw material for the production of highly elastic spandex (Lycra fiber). Spandex is mainly used in the production of high-elasticity knitwear such as advanced sportswear and swimwear.

The downstream product of 1,4-butanediol, γ-butyrolactone, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone, from which a series of high value-added products such as vinylpyrrolidone and polyvinylpyrrolidone are derived. Widely used in pesticides, medicine and cosmetics and other fields.
