<p>The present invention provides a process 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, wherein the temperature in the reaction vessel is kept between 0 and 20.degree.C. by cooling, 1.0 to 3% by weight of hydrogen peroxide, referred to the total amount of the reaction batch, and sodium hydroxide in an amount such that the concentration thereof in the reaction mixture running off is 0.15 to 0.30N are added thereto, the reaction mixture withdrawn from the reaction vessel is heated, by the addition of water, at a temperature of from 70 to 90.degree.C., to above the melting temperature of lauroyl peroxide and the molten lauroyl peroxide is separated off in a separator.</p> |
