| 摘 要： | 本文用自合成的Ti-MCM-41分子筛为催化剂，苯酚和H2O2直接氧化法合成苯二酚。用化学分析和色谱分析来确定H2O2的分解率、利用率、苯酚的转化率、苯二酚的选择性。反应温度70℃、反应时间7h、进料比：n（苯酚）In（H2OM2）=3：1；n（苯酚）／n（Ti-MCM-41）=10：1是较为理想的条件。

| Abstract: | Using the synthetic Ti-MCM-41 Molecular Sieve as catalyst, phenol and H2O2 were synthesized into dihydroxybenzene by directed Oxidation. Chemical analysis and chromatographic analysis were used to determine the decomposition rate and usage of H2O2 , the conversion rates of phenol, and the selectivity of dihydroxybenzene. The ideal reaction conditions included： reaction temperature of 70℃ , reaction time 7 h. charge proportion; n（ Phenol）/n（ H2O2 ） = 3： 1, n（ Phenol）/n（Ti-MCM-41 ） = 10： 1. |
