ABSTRACT:
The invention provides an improvement for the continuous preparation of lauroyl peroxide in the absence of organic solvents from crude lauroyl chloride, aqueous sodium hydroxide solution and hydrogen peroxide by continuously adding the reaction components to a reaction stirrer vessel and carrying out the reaction with an average residence time of 15 to 30 minutes, the improvement comprising maintaining the temperature in the raction vessel between 0.degree. and 20.degree. C. by cooling, adding 1.0 to 3% by weight of hydrogen peroxide, referred to the total amount of the reaction mixture, and sodium hydroxide in such amount that the concentration thereof in the reaction mixture run off is 0.15 to 0.30N, withdrawing the reaction mixture from the reaction vessel and heating the reaction mixture by the addition of water of a temperature of from 70.degree. to 90.degree. C., to above the melting point of lauroyl peroxide, and separating off the molten lauroyl peroxide in a separator.
