The hydration of phenylacetylene in near-critical water, assisted with additives (NaHSO₄, ZnCl₂, FeCl₃), has been successfully conducted with temperature and residence time ranges of 220-300℃ and 60-180 min, respectively. The results showed the catalytic ability is FeCl₃ > ZnCl₂ > NaHSO₄. The maximum yield of product acetophenone was 96.68% at 260℃, 120 min. Based on the results found, a possible mechanism of hydration of phenylacetylene in near-critical water was proposed.
