Abstract
Process for the preparation of surfactants, from hydroxy compounds, fatty acid esters and alkylene oxides, characterized in that it simultaneously comprises reacting one or more mono- or poly-hydroxylated aliphatic or cycloaliphatic organic substances, having from 1 to 18 carbon atoms, one or more fatty acids having from 6 to 30 carbon atoms esterified with one or more mono- or polyhydric aliphatic alcohols having from 1 to 18 carbon atoms and one or more alkylene oxides having from 2 to 4 carbon atoms, in the presence of an alkylene catalyst, at a temperature comprised between 70 and 200º C and at a pressure comprised between 1 and 50 atmospheres.
