Method of manufacturing sulfonium salt

摘要

Provided is a sulfonium salt manufacturing method which can reduce the production of a monosulfonium salt. A method of manufacturing a sulfonium salt includes preparing a first sulfonium salt containing a sulfonium cation and a first anion, preparing a second sulfonium salt by exchanging the first anion for a halide ion, and preparing a third sulfonium salt by exchanging the halide ion for a second anion.
