目前世界四氢呋喃的生产能力达到了41.1万t/a,BASF和DuPont的四氢呋喃产量占世界总产量的55％。世界80％的四氢呋喃用于合成聚亚甲基醚二醇,进一步合成热塑性聚氨酯、共聚酯醚和聚氨酯弹性纤维。聚亚甲基醚二醇的需求增长较快,是四氢呋喃未来的主要消费领域。国内现有四氢呋喃生产能力难以满足日益增长的市场需求,而且还包括许多面临淘汰的小规模装置,我国四氢呋喃有较大的发展潜力。
At present, the production capacity of tetrahydrofuran in the world reaches 411,000 t / a, while that of BASF and DuPont accounts for 55% of the world total. 80% of the world’s tetrahydrofuran for the synthesis of poly (ethylene ether glycol), further synthesis of thermoplastic polyurethane, copolyester ether and polyurethane elastic fibers. The demand for polymethylene ether glycol has increased rapidly and is the main area of consumption for tetrahydrofuran in the future. The existing domestic THF production capacity is difficult to meet the growing market demand, but also many small-scale facilities are facing elimination, China’s tetrahydrofuran has great potential for development.
