  • Method for making diarylhalonium salts
    Patent number: 4151175
    Abstract: A method is provided for making certain diaryliodonium salt photoinitiators, based on the initial formation of a diaryliodonium bisulfate. Methylene chloride is substituted for acetic acid during the reaction between potassium iodate and benzene in the presence of acetic anhydride and sulfuric acid. The diaryliodonium bisulfate is then reacted with a counterion source, such as a metal salt, to produce the desired diaryliodonium salt which can be used as a photoinitiator. The iodonium salt photoinitiators made by the method of the present invention can be used to make UV curable compositions.
