Use | Used as a polymerization initiator for styrene-butadiene rubber Used as an initiator for the polymerization of styrene-butadiene rubber, its initiation speed is higher than that of cumene hydroperoxide 30% ~ 50% faster, but slower than tricumene hydroperoxide and tert-butylcumene hydroperoxide. It can also be used as an initiator for other polymers. This product will cause burns when it comes into contact with the skin. |
production method | this product is an intermediate by-product of cumene oxidation to phenol acetone: in cumene prepared by the reaction of benzene and propylene, the concentration of dicumene is generally about 11%. The dicumyl benzene is directly oxidized with air at a temperature of 110~120 ℃ and a pressure at the top of the oxidation tower of about 0.3MPa to obtain an oxidation solution of dicumyl hydrogen peroxide, which is then concentrated to 50% ~ 60% under reduced pressure, I .e. as a product with a relative density of (20/4 ℃)0.935~0.960 and a refractive index of 1.4880~1.510. |
