聚四氢呋喃生产技术的发展及对我国研究开发现状的思考

Advances in production technology for polytetrahydrofuran and consideration about R&D in China

详述了全球5种聚四氢呋喃生产工艺,包括高氯酸催化剂工艺、氟磺酸催化剂工艺、Nafion树脂催化剂工艺、活性蒙脱土催化剂工艺和杂多酸催化剂工艺。分析了各种工艺的优势和不足,综述了今后发展的趋势。我国将成为聚四氢呋喃的生产和消费大国,针对我国虽经多年研究开发,但未能形成工业生产技术的现状,分析了原因并提出了看法。

Five processes for production of polytetrahydrofuran are introduced as follows:catalyzed by ①perchloric acid,②flurosulfonic acid,③Nafion resin,④activated montmorillonite,and ⑤heteropolyacids.The superiorities and defects of various technologies are analyzed,and their development trends are summarized.Though China has become the largest producer and consumer of polytetrahydrofuran,over many years of R&D,these processes have not yet achieved a commercial scale of production in China.The causes are analyzed and means for resolution is suggested.
