Reaction Steps

The reaction is effected in a reactor arrangement of a first reactor of type E with a downstream reactor of type C. Before the start of the reaction, the first reactor is filled with a solution of 25.8% by weight of tert-butyl hydroperoxide and 16.4% by weight of potassium hydroxide in water. 24.6 kg/h of a solution of 70% by weight of tert-butyl hydroperoxide in water, 24.2 kg/h of a solution of 45% by weight of potassium hydroxide in water, 17.4 kg/h of water and 24.0 kg/h of 2-ethylhexanoyl chloride are then fed to the first reactor. Cooling with cooling water keeps the internal temperature in the first reactor at 35° C. and in the second reactor at 27° C. The organic phase is removed from the reaction mixture withdrawn from the second reactor. The organic phase is 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 a 1% by weight solution of sodium hydrogencarbonate in water, and then dried by stripping in a column with random packing at 33° C. and 35 to 40 mbar. 31.4 kg/h of tert-butyl peroxy-2-ethylhexanoate are obtained (98.5% based on 2-ethylhexanoyl chloride). The space-time yield is 2.53 kg/l·h.
