Abstract: 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.

Abstract: Described herein is an etheramine mixture including at least 90% by weight, based on the total weight of the etheramine mixture, of an amine of Formula (I) and/or (II), wherein R1-R12 are independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, wherein at least one of R1-R6 and at least one of R7-R12 is different from H, wherein A1-A9 are independently selected from linear or branched alkanediyl groups having 2 to 18 carbon atoms, wherein Z1-Z4 are independently selected from —OH and linear —OCH2CH2CH2NH2, wherein the degree of amination of each of the etheramines of Formula (I) and Formula (II) is at least 50%, and wherein the sum of x+y is in the range of from 2 to 200, wherein x≥1 and y≥1; and x1+y1 is in the range of from 2 to 200, wherein x1≥1 and y1≥1.

Abstract: An etheramine mixture comprising of at least one amine selected from the group consisting of amine of Formula (I) and amine of Formula (II) wherein R1-R12 are independently selected from H, alkyl, cycloalkyi, aryl, alkylaryl, or arylalkyi, wherein at least one of R1-R6 and at least one of R7-R12 is different from H, and wherein Z1-Z3 are linear CH2CH2CH2NH2.
