摘要：

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。

Abstract:

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 recycling 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.
