Preparation, Characterization and Catalytic Application for the Synthesis of Tetrahydrofuran

Abstract

1,4-butanediol condensation can be performed with Cs-W - HPA. Cs2H4P2W18O62showed excellent catalytic performance for preparation of THF. In the optimal conditions, the reaction temperature was 180 °C, the reaction time was 43 min, catalyst dosage was 0.4 g, THF yield could reach 89.4%. And reused five times, the yield could reach 83.2%. HPA had the very good application prospect.
