PROCESS FOR PRODUCING TETRAKISFLUOROPHENYLBORATE

摘要

An efficient process for producing a tetrakisfluorophenylborate, useful as an olefin polymerization catalyst component or a starting material therefor, at a high production rate per unit solvent and a high yield according to the following reaction formula, wherein a mixture of ether with an aliphatic hydrocarbon is used as the reaction solvent: 4M4-C6Y35+BCl3->M4B(C6Y35)4, wherein M4 represents an alkali metal, an alkaline earth metal or R62Al (wherein R6 represents alkyl); and Y3 represents hydrogen or halogen.
