| 摘 要： | 研究镁铝钴复合氧化物新型催化剂的合成，并以此催化剂催化合成农产品保鲜新材料环氧乙烷高级脂肪醇（OHAA）。薄层色谱表明镁铝钴复合氧化物催化合成的OHAA分布指数达到80%以上，具有很好的窄分布效果。通过催化剂用量、反应温度、反应压力三者间的L9(33)正交试验，得出镁铝钴复合氧化物催化OHAA合成的最佳反应条件为催化剂用量3%，温度160℃, 压力0.6 MPa。

| Abstract: | In this paper, we studied the synthesis of a new type catalyst Mg-Al-Co metal compound oxide, then with this catalyst to synthesize a new fresh keeping material OHAA for agricultural products. TLC result showed that the distribution index of OHAA catalyzed by Mg-Al-Co compound oxide reached over 80% with very good narrow distribution effect. The L9(33) orthogonal experiments were made to investigate the best reaction conditions. The best reaction conditions of OHAA synthesis by Mg-Al-Co compound oxide catalyst were 3% of catalyst amount, 160 ℃ of temperature and under the pressure of 0.6 MPa. |
