摘　　要：以活性炭负载过渡金属混合物为催化剂,采用液相多相催化氧化合成对羟基苯甲醛,筛选出了优良的催化剂,研究了合成对羟基苯甲醛的最佳反应条件,在最佳反应条件下,对羟基苯甲醛的收率稳定在80%以上。The liquid-phase heterogeous catalytic oxidation of p-cresol to p-hydroxybenzaldehyde was investigated by using transition metals carried on active carbon as catalyst.The suitable catalysts were selected and the optimal reactive condition was determined. The yield of p-hydroxybenzaldehyde,under the optimal reactive condition, was over 80% steadily.
