1, 4-butanediol mainly has three industrial chains.
(1) Tetrahydrofuran production, accounting for about 60% of the consumption of 1, 4-butanediol, tetrahydrofuran through ring-opening polymerization to produce poly (PTMEG), pharmaceutical intermediates or directly used as solvents;
(2) production of γ-butanediol, about 20% of the consumption of 1, 4-butanediol, γ-butanediol and acetylene production of 2-pyrrolidone, vinyl pyrrolidone and polyethylene pyrrolidone;
(3) the production of PBT resin for home appliance industry, color TV industry; About 9% of the consumption of 1, 4-butanediol. The production of 1, 4-butanediol has been greatly increased and it has become an important basic organic chemical product.
Main application fields of 1, 4-butanediol.
(1) As a solvent, it can be used in medicine, fragrance and chemical industries;
(2) As a chemical raw material, can produce polytetramethyleneglycol PTMEG, tetrahydrothiophene, pyronolane ketone, 2, 3-dichlorotetrahydrofuran, 1, 4-dichloroethane, butylene lipid, pentose lipid, ink and flavor, etc;
(3) Production of polyether, polyurethane ultra-soft elastic fiber and high elastic rubber is the best material.
