Product Name:Lauroyl peroxide
CAS Number:105-74-8
Molecular formula:C24H46O4
Molecular Weight:398.62

Dilauroyl peroxide is the symmetrical peroxide of lauric acid. It is produced by treating lauroyl chloride with hydrogen peroxide in the presence of base:
2C11H23COCl + H2O2+ 2NaOH → (C11H23CO2)2 + 2HCl

Reaction Conditions:

with dihydrogen peroxide;sodium hydroxide in 2-Methylpentane;lithium hydroxide monohydrate at 16 - 18; for 0.666667 h;

Steps:

1 Production of Powdered Lauroyl Peroxide

1250 g water, 42 g (0.86 mol) hydrogen peroxide70%, 252 g (1.58 mol) caustic soda lye 25% and 60 g isohexane are provided and cooled to 16° C. 240 g (1.10 mol) lauric acid chloride are added dropwise, over 20 minutes while cooling, at temperatures of from 16 to 18° C. Following the addition, the reaction mixture is stirred for a further 20 minutes at the same temperature. Said mixture is filtered using a Nutsche filter and the solid matter obtained is repeatedly washed using a total of 4 litres of watet 291 g of product damp from water is obtained having a content of 75%, which corresponds to a yield of 98%. After drying in air or in a vacuum, the lauroyl peroxide content was 99.1%. The chlorine content in the product is 60 ppm, the lauric per-acid content is 0.01%.
