AI Technical Summary
Technical Problem
Existing catalysts for the preparation of tetrahydrothiophene via the tetrahydrofuran method are costly, have low conversion rates, and involve complex processes, making them difficult to meet industrial needs.
Method used
A sol-gel was prepared by mixing copper-containing compounds, heteropolyacid salts, and alumina precursors via microwave reaction, followed by calcination to obtain a catalyst. This catalyst was used for the direct sulfidation of tetrahydrofuran to tetrahydrothiophene. The reaction conditions were mild, the selectivity was high, the operation was simple, and the cost was low.
Benefits of technology
Achieving 100% conversion of tetrahydrofuran and 99.5% selectivity for tetrahydrothiophene significantly improves the efficiency and economy of the catalyst.

Abstract
本发明提出了一种四氢呋喃直接硫化制四氢噻吩用催化剂、制备方法和应用，所述催化剂能有效降低四氢噻吩生产成本，同时替代传统贵金属‑杂多酸型催化剂。以四氢呋喃和硫化氢为原料合成四氢噻吩，且整个生产过程仅有副产物水产生，不产生其他污染物。该催化剂将含铜化合物、杂多酸盐与氧化铝前驱体混合、搅拌、微波反应制得溶胶凝胶，再经干燥制得催化剂前驱体，催化剂前驱体焙烧制得催化剂。经过催化性能评价，催化剂的四氢呋喃转化率最大值为100%和四氢噻吩选择性最大值为99.5%。
