We performed the Rupe rearrangement of 1-ethynylcyclohexan-1-ol in near-critical water to study the reaction under high temperature conditions. The final product thus obtained was primarily 1-cyclohexen-1-ylethanone which was identified by GC-MS. The influences of reaction time, temperature, and initial reactant-to-water ratio on the yield of 1-cyclohexen-1-ylethanone were examined. The yield of 1-cyclohexen-1-ylethanone...
The hydration of phenylacetylene in near-critical water, assisted with additives (NaHSO 4 , ZnCl 2 , FeCl 3 ), has been successfully conducted with temperature and residence time ranges of 220–300°C and 60–180min, respectively. The results showed the catalytic ability is FeCl 3 >ZnCl 2 >NaHSO 4 . The maximum yield of product acetophenone was 96...
