Dehydration of sorbitol to isosorbide on solid acid catalyst
摘要
Abstract
Dehydration of sorbitol to isosorbide on various solid acids was investigated to improve isosor-bide yield. The results showed that the catalytic performances of solid acids were closely related to their acidities. H3PO4/Nb2O5 catalyst with stronger acidity showed better catalytic performance than other solid acids. The 100% sorbitol conversion and 63% isosorbide selectivity was obtained on H3PO4/Nb2O5 catalyst with n(P)/n(Nb) =0.8.关键词
