A method for the production of onium - salts with dialkyl phosphate -, dialkyl phosphinate or (o - alkyl) - alkyl - or alkyl - phosphonate - anions with a low halide - content

摘要

The present invention relates to a process for the preparation of onium - salts with dialkyl phosphate -, dialkyl phosphinate - or (o - alkyl) - alkyl - or alkylphosphonate - anions by reaction of an onium - halide with a phosphorus acid trialkyl esters, a dialkyl phosphine acid alkyl ester, a phone alkyl phosphoric acid dialkyl ester or a trialkylsilyl esters or mixtures of alkyl - trialkylsilyl esters of the phosphorus -, dialkyl phosphine - or alkylphosphonic acid.
