Title:
POLYMERIZATION INITIATOR COMPOSITION AND PRODUCTION METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020117441
Kind Code:
A
Abstract:
To provide a polymerization initiator that can be handled more safely than a solid and contains PFBPO, and to provide a production method that can produce the polymerization initiator containing such PFBPO at a higher yield, can suppress fastening to a reactor and has excellent applicability to an actual production process.SOLUTION: A production method of a PFBPO-containing solution includes steps of: obtaining a solution containing bis(perfluorobenzoyl)peroxide(PFBPO) by reacting pentafluorobenzoyl chloride (PFBC) and a peroxide in an organic solvent and under coexistence of an alkaline aqueous solution and ; obtaining a PFBPO-containing solution as an organic phase, by separating the obtained PFBPO-containing solution into an aqueous phase and the organic phase. A polymerization initiator composition containing the PFBPO and a fluorine-containing solvent.SELECTED DRAWING: None
