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.
