Cumene hydroperoxide is an organic compound from the group of hydroperoxides, which is derived from cumene. It is a colorless to yellow liquid with a faint, aromatic odor.

Properties

The vapors of cumene hydroperoxide are 5.26 times heavier than air. It has a viscosity of 12 mPa · s at 20 ° C.

Use

Cumene hydroperoxide occurs ( for example, when acetone and phenol according to the cumene synthesis method) as an intermediate in the synthesis of organic compounds.

In the manufacture of plastics, it is used as a starter or activator for curing some resins that polymerize via a radical chain mechanism.

Safety

Cumene hydroperoxide decomposes slowly even at room temperature. At higher temperatures, the decomposition rate increases ( from 80 ° C ) up to the explosion ( from 109 ° C).
