Patent ID: 6989038

Claim:
A mixture of sulfuric esters of formula (1) wherein R 1 is an aliphatic radical having 1 to 30 carbon atoms, R 2 is a radical of formula (2) wherein n is an integer from 0 to 30, m is an integer from 1 to 29, X is an aliphatic radical having 4 to 24 carbon atoms, and Y is H or SO 2 (OM), where M represents hydrogen, alkali metal, ammonium, mono-, di-, tri-, or tetra(C 1 -C 6 -alkyl)ammonium, or mono-, di-, tri-, or tetra(C 2 -C 6 -alkanol)ammonium ions, R 3 is a radical of formula (3) wherein p is an integer from 4 to 35, R 4 is H, methyl, ethyl, phenyl, or mixtures of H and methyl, and Z is H, methyl, ethyl, or SO 2 (OM), where M represents hydrogen, alkali metal, ammonium, mono-, di-, tri-, or tetra(C 1 -C 6 -alkyl)ammonium, or mono-, di-, tri-, or tetra(C 2 -C 6 -alkanol)ammonium ions, and a, b, and c are identical or different and are 0, 1, or 2, with the proviso that a+b+c is 2, obtained by reacting sulfuryl chloride with a mixture of the alcohols R 1 OH, R 2 OH, and R 3 OH, wherein R 1 , R 2 , and R 3 have the same meanings as for formula (1) except that Y is exclusively hydrogen and Z is hydrogen, methyl, or ethyl.
