考察了几种钴的β—二酮络合物对环巳烷液相氧化反应的催化活性。实验表明,在环巳醇和环巳酮选择性为75%左右时,环巳烷转化率可达6～7%,比现在工业上采用的环烷酸钴催化剂的活性稍高一些。反应温度及仃留时间对上述指标影响较大。温度控制在145℃以上,反应时间30分钟较好。 The catalytic activities of several cobalt-β-diketonate complexes for the liquid phase oxidation of cyclohexane were investigated. Experiments show that when the selectivity of Cyclamate and Cyclamate is about 75%, the conversion of Cyclohexane can reach 6 ~ 7%, which is slightly higher than that of cobalt naphthenate catalyst currently used in the industry. The reaction temperature and retention time of the above indicators have a greater impact. Temperature control above 145 ℃, the reaction time of 30 minutes is better.
