Abstract
A process is disclosed for the preparation of granular or pulverulent organic peroxides which are solid at temperatures ranging from -20.degree. to 55.degree.C by solidifying the peroxide in liquid form with a liquid cooling medium which at most hardly dissolves the peroxide, which is liquid at a temperature of -20.degree.C or lower, and which is gaseous at the storage temperature of the peroxide to be solidified. An example of the liquid cooling medium is liquid nitrogen and an example of the organic peroxide is diisopropylperoxydicarbonate. The present process permits the formation of granular or pulverulent solid organic peroxides without traces of liquid peroxide which can cause safety problems.
