tert-Butyl hydroperoxide → tert-Butyl peroxybenzoate

Participants

Reaction Steps

The reaction is effected in a reactor arrangement of a first reactor of type D with two reactors of type B connected downstream in series. 1.72 kg/l·h of a 19.5% by weight solution of tert-butyl hydroperoxide and 9.5% by weight of sodium hydroxide in water and 0.49 kg/l·h of benzoyl chloride are fed to the first reactor. The metering rates are based on the total volume of the reactor arrangement in litres. Cooling with cooling water keeps the internal temperature in all reactors at 25° C. The organic phase is removed from the reaction mixture withdrawn from the third reactor, washed successively with an 8% by weight solution of sodium hydroxide in water, with a solution of 10% by weight of sodium sulphite in water comprising acetic acid and with demineralized water, and then dried with calcium chloride. 0.61 kg/l·h of tert-butyl peroxybenzoate is obtained (89.9% based on benzoyl chloride).
