丁二醇主要用作化学中间体,最大用量的衍生物为四氢呋喃(THF),其次是工程塑料聚对苯二甲酸丁二醇酯(PBT)和γ-丁内酯(GBL)衍生物。THF可用于生产聚四亚甲基醚乙二醇(PTMEG),主要用于斯潘德克斯弹性纤维(氨纶)、聚氨酯弹性体和共聚酯,其他用途有:溶剂、涂层树脂和医药中间体。在全球丁二醇消费量中,THF占35％,PBT占34％,GBL占12％,TPU占12％,COPE占
Butylene glycol is mainly used as a chemical intermediate. The maximum amount of derivative is tetrahydrofuran (THF), followed by engineering plastic polybutylene terephthalate (PBT) and γ-butyrolactone (GBL) derivatives. THF is used in the production of polytetramethylene ether glycol (PTMEG), primarily for spandex, polyurethane elastomers and copolyesters. Other uses include solvents, coating resins and pharmaceutical intermediates . Among the global butanediol consumption, THF accounts for 35%, PBT 34%, GBL 12%, TPU 12% and COPE
