More Information
Summary:The present invention relates to a process for the synthesis of organosulfate salts of amino acid esters comprising the steps of reacting at least one lactam with at least 3 carbon atoms in the lactam ring with sulfuric acid in an aqueous solution followed by esterification of the reaction product of the previous step with at least 200 mol-% of at least one alcohol selected from the group consisting of linear alkyl alcohol containing one hydroxy group, branched alkyl alcohol containing one hydroxy group, linear alkylether alcohol containing one hydroxy group, branched alkylether alcohol containing one hydroxy group, phenoxyalkanols containing one hydroxy group, and mixtures thereof; followed optionally removal of water and/or removal of excess alcohol.
