Cumene hydroperoxide is an organic compound from the group of hydroperoxides , which is derived from cumene . It is a colorless to yellowish liquid with a slightly aromatic odor.
properties
Cumene hydroperoxide has a viscosity of 12 mPa · s at 20 ° C. Cumene hydroperoxide vapors are five times as heavy as air.
use
Cumene hydroperoxide occurs as an intermediate product in the synthesis of organic compounds (e.g. in acetone or phenol synthesis using the cumene hydroperoxide process ).
In plastics production, it serves as a starter or activator for the hardening of some resins that polymerize via a radical chain mechanism.
safety instructions
Cumene hydroperoxide decomposes slowly even at room temperature . At higher temperatures, the rate of disintegration increases (from 80 ° C) up to explosion (from 109 ° C).
