Abstract
Peroxydicarbonates are widely used as initiators in the polymerizations of vinyl monomers. In the past, they can be prepared by reaction of chloroformate with hydrogen peroxide and aqueous sodium hydroxide solution directly, or in inert solvents, such as chlorinated hydrocarbon or IP-1620 (aliphatic hydrocarbons). In the former process, the handling is dangerous, because of the highly sensitivity of the products, and the yields are relatively low due to the high viscosity of the reacted solution. In the later precess, chlorinated hydrocarbon have a high potential for destroying ozone in the stratosphere. Besides, use IP-1620 as inert solvent, the concentration of both H2O2 and NaOH should be very high. The present invention relates a process for the manufacture of peroxydicarbonates by reaction of chloroformate with 15.7% H2O2, 25% NaOH and little amount of lower alcohol in aliphatic hydrocarbons.
