Claims21
A mixture of sulfuric esters of formula (1)
- wherein
- R1 is an aliphatic radical having 1 to 30 carbon atoms,
- R2 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 SO2(OM), where M represents hydrogen, alkali metal, ammonium, mono-, di-, tri-, or tetra(C1-C6-alkyl)ammonium, or mono-, di-, tri-, or tetra(C2-C6-alkanol)ammonium ions,
- R3 is a radical of formula (3)
- wherein
- p is an integer from 4 to 35,
- R4 is H, methyl, ethyl, phenyl, or mixtures of H and methyl, and
- Z is H, methyl, ethyl, or SO2(OM), where M represents hydrogen, alkali metal, ammonium, mono-, di-, tri-, or tetra-(C1-C6-alkyl)ammonium, or mono-, di-, tri-, or tetra(C2-C6-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 R1OH, R2OH, and R3OH, wherein R1, R2, and R3 have the same meanings as for formula (1) except that Y is exclusively hydrogen and Z is hydrogen, methyl, or ethyl.
