The invention relates to a method for producing polyolalkylethers by reacting at least three compounds having hydroxy functions with olefins in the presence of acidic catalysts at temperatures of between 20 - 250 °C and pressures of between 0,5 - 10 bar. The olefins correspond to general formula (I), wherein R<SUP>1</SUP> represents hydrogen and R<SUP>2</SUP> is linear or branched carbon radicals having 7 - 28 carbon atoms, or R<SUP>1</SUP> and R<SUP>2</SUP> respectively represent linear or branched carbon radicals having 1 - 27 carbon atoms, whereby the number of carbon atoms of R<SUP>1</SUP> and R<SUP>2</SUP> is, at maximum, 28. The invention also relates to polyolalkylethers which are derived from compounds having at least three hydroxy functions, or all hydroxy functions until one is replaced by a grouping of general formula (VIII). The invention further relates to said polyolalkylethers as surfactants and said washing and cleaning agents containing polyolalkylethers. |
