^{Applifications:}

^{1, 4-butanediol is an important organic chemical and fine chemical raw material, which is the basic raw material for the production of polybutanediol terephthalate (PBT) engineering plastics and PBT fiber. PBT plastic is one of the five most promising engineering plastics.

1,4 butanediol is the main raw material for the production of tetrahydrofuran, tetrahydrofuran is an important organic solvent, and polytetramethylene glycol ether (PTMEG) obtained after polymerization is the basic raw material for the production of high elastic spandex (Lycra fiber). Spandex is mainly used in the production of high elastic knitwear such as sportswear and bathing suits.

The downstream product of 1,4 butanediol, gamma-butanolactone, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone products, from which a series of high value-added products such as vinylpyrrolidone and polyethylpyrrolidone are widely used in the fields of pesticides, medicine and cosmetics.}
