PROCEDIMIENTO PARA LA OBTENCION DE ALCOXILATOS DE ALCOHOLES GRASOS.

摘要

The invention relates to a method for the preparation of fatty alcohol alkoxylates by alkoxylation of monovalent aliphatic alcohols with 6 to 24 C atoms or esters from hydroxycarboxylic acids with 6 to 24 C atoms and monovalent or polyvalent alcohols with alkylene oxides in the presence of a double metal cyanide catalyst, containing a double metal cyanide complex compound of general formula (I): M<1>a[M<2>(CN)b(A)c]d . fM<1>gXn . h(H2O). eL, wherein M<1> and M<2> represent certain metal ions which are identical or different; A and X represent anions from the group consisting of halogenide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate or nitrate; L represents a ligand that may be mixed with water from the group consisting of alcohols, aldehyde, ketone, ether, polyether, ester, urea, amide, nitrile and sulfide, wherein a, b, c, d, g and n are selected in such a way that electroneutrality of the compound is guaranteed, e represents a coordination number of the ligand and f and h represent a fractional or whole number higher than 0 or equal 0.
