Abstract
A process for preparing a tetrakisfluorophenylborate which is useful as a catalyst component for the polymerization of olefins or as a raw material for synthesizing the same, efficiently at a high productivity per unit amount of a solvent and at a high yield. A mixed solvent of ether and an aliphatic hydrocarbon is used as a reaction solvent for preparing tetrakisphenylborate according to the following reaction formula, 4M.sup.4 --C.sub.6 Y.sup.3.sub.5 +BCl.sub.3 .fwdarw.M.sup.4 B(C.sub.6 Y.sup.3.sub.5).sub.4 wherein M.sup.4 is an alkali or alkaline earth metal, or represents R.sup.6.sub.2 Al, wherein R.sup.6 is an alkyl group, and Y.sup.3 is a hydrogen atom or a halogen atom.
