Sulphatizated hydroxy-mixed ethers, process for their preparation and their use.

摘要

Sulphated hydroxyalkylpolyethylene and hydroxyalkylpolypropylene glycol ethers of the formula (II) …… in which… R<1> represents a linear alkyl radical having 1 to 16 carbon atoms,… R<2> represents a linear or branched, saturated alkyl radical having 1 to 22 carbon atoms,… R<3> represents hydrogen or a linear alkyl radical having 1 to 16 carbon atoms,… R<4> represents hydrogen or a methyl group,… M represents hydrogen, ammonium, alkylammonium, alkanolammonium, in which the alkyl and alkanol radicals each have 1 to 4 carbon atoms, or represents a monovalent metal atom, and… n represents a number in the range from 1 to 30,… with the proviso that the total number of the carbon atoms contained in R<1> and R<3> is 6 to 16, and mixtures of several compounds of this type, a process for the preparation of the compounds of the formula (II) from the corresponding hydroxyalkylpolyethylene and hydroxyalkylpolypropylene glycol ethers by reaction with gaseous sulphur trioxide or chlorosulphonic acid at elevated temperature and the use of the sulphated compounds or mixtures thereof as wetting agents and detergent raw materials or cleaning agent raw materials.
