The invention relates to a process of producing carbonate esters wherein an alkyl chloroformate is reacted with a phenolsulfonate in an alkaline medium and discloses the improvement whereby dialkylcarbonate formation is reduced by adding an acidifying agent to the reaction mixture after the reaction and before precipitation of the alkylsulfophenyl carbonate.

A process is described for obtaining sulfophenyl quaternary ammonium or phosphonium substituted carbonic acid esters. These esters are prepared through sulfonation with sulfur trioxide of aromatic chloroformates followed by reaction of the sulfonated aromatic chloroformate with quaternary ammonium or phosphonium substituted alcohols. The resultant sulfophenyl esters are useful as bleach precursors in combination with peroxygen compounds such as sodium perborate or percarbonate.
