Abstract
Polyadducts of an alkylene oxide and styrene oxide with an aryl alcohol, especially polyadducts of formulae ##STR1## wherein the ring A is an unsubstituted phenyl radical or a phenyl radical which is substituted by halogen, methyl or C.sub.1 -C.sub.3 alkoxy, Q.sub.1 is alkylene of 1 to 4 carbon atoms, preferably methylene, in the pairs of substituents (Y.sub.1 and Y.sub.2) and (Y.sub.3 and Y.sub.4) one Y is phenyl and the other Y is hydrogen, "alkylene" denotes an alkylene radical of 2 or 3 carbon atoms, and m is an integer from 1 to 80. These polyadducts are a novel class of nonionic or anionic surfactants which are used as textile auxiliaries.
Claims14
A polyadduct of an alkylene oxide and styrene oxide with an aryl alkanol, or a phosphoric, maleic, sulfo succinic, of sulfuric acid ester of said polyadduct or a salt thereof selected from the group consisting of the formulas ##STR28## wherein the ring A is phenyl or phenyl substituted by halogen, methyl or C.sub.1 -C.sub.3 alkoxy,
- Q.sub.1 is alkylene of 1 to 4 carbon atoms,
- one of Y.sub.1 and Y.sub.2 is phenyl and the other is hydrogen,
- in the pairs of substituents (Y.sub.1 and Y.sub.2) and (Y.sub.3 and Y.sub.4) in formula (2) one Y is phenyl and the other Y is hydrogen,
- "alkylene" denotes an alkylene radical of 2 or 3 carbon atoms, and
- m is an integer from 1 to 80.
An acid ester of formula ##STR35## wherein the ring A is an unsubstituted phenyl radical or a phenyl radical which is substituted by halogen, methyl or methoxy, one of Y.sub.1 and Y.sub.2 is phenyl and the other is hydrogen, one of Z.sub.1 and Z.sub.2 is methyl and the other is hydrogen, X is the acid radical of maleic acid, sulfosuccinic acid, sulfuric acid or phosphoric acid, and the sum of n.sub.1 +n.sub.2 is 2 to 30.
An acid ester of formula ##STR36## wherein the ring A is an unsubstituted phenyl radical or a phenyl radical which is substituted by halogen, methyl or methoxy, one of Y.sub.1 and Y.sub.2 is phenyl and the other is hydrogen, one of Z.sub.1 and Z.sub.2 is methyl and the other is hydrogen, X is the acid radical of maleic acid, sulfosuccinic acid, sulfuric acid or phosphoric acid, and the sum of n.sub.1 +n.sub.2 is 2 to 30.
