Amberlyst-15催化丁酮氧化制备过氧化甲乙酮

Amberlyst-15 Catalyzed Oxidation of Butanone to Methyl Ethyl Ketone Peroxide

作为一种新型绿色催化剂,离子交换树脂能够代替某些有机反应中的传统催化剂。本文以离子交换树脂Amberlyst-15为催化剂,由30%的双氧水、丁酮和稀释剂邻苯二甲酸二丁酯合成过氧化甲乙酮。在双氧水与丁酮的摩尔比为1.0,离子交换树脂与丁酮的质量比为0.06,反应温度为27℃,反应时间55 min的条件下,过氧化甲乙酮的产率接近86%,活性氧含量为12.9%。Amberlyst-15在循环使用8次后,依然保持良好的稳定性。研究表明:Amberlyst-15用于过氧化甲乙酮的制备具有催化活性高、可重复使用、清洁无腐蚀等优点,为工业环保生产有机过氧化物提供了新途径。

Ion exchange resin, as a new green catalyst, can replace traditional catalysts used in series of organic reaction. In this paper, methyl ethyl ketone peroxides （MEKP） were synthesized by oxidation of methyl ethyl ketone using 30% hydrogen peroxide as oxidant, dibutyl phthalate as diluent and Amberlyst-15 as catalyst. Under the conditions that the molar ratio of hydrogen peroxide to methyl ethyl ketone is of 1.0, mass ratio of Amberlyst-15 to methyl ethyl ketone is of 0. 06, the reaction temperature at 27 ℃ and reaction time for 55 min, the yield of methyl ethyl ketone peroxide can reach 86%, and activated oxygen content is 12. 9%. Amberlyst-15 still keep good stability after recychng for 8 times. This study shows that Amberlyst-15 has the advantages of high catalytic activity, good repeated utilization, cleaning and low corrosivity. The method developed can be a new way for the production of MEKP.
