    Second, the product is introduced Properties: 1, 4 - butanediol (BDO) is a colorless oily combustible liquid, can be immiscible with water, but soluble in methanol, ethanol, acetone, slightly soluble in ether. Boiling point 235 ℃, melting point is 20.1 ℃, flash point (opening) 121 ℃, the relative density (d4-20) 1.017, temperature 370 ℃, the refractive index of 1.446. Purpose: 1.1, 4 - butyl glycol is a kind of important organic chemical and fine chemical raw materials, it is the production of poly (butyl glycol terephthalate (PBT) engineering plastics and the basic materials of PBT fiber, and PBT plastic is one of the most promising five engineering plastics. 2.1, 4 - butyl glycol is the production of tetrahydrofuran (THF), the main raw material. Tetrahydrofuran is an important organic solvent, the aggregate production of poly (tetramethylene ether glycol (PTMEG) is the basic material in the manufacture of the high elasticity of spandex. Spandex mainly for the production of sportswear, swimwear high elastic fabrics. 3.1, 4 - butyl glycol is the production of gamma butyrolactone main raw material. Gamma butyrolactone mainly for the production of alpha - pyrrolidone
