ABSTRACT:
A process for the preparation of carboxylic acid esters of linear aliphatic polyalcohols or of hydrophilic derivatives of these polyalcohols containing a minimal percentage of anhydrocompounds, the process comprising esterifying an aliphatic fatty acid having 10 to 22 carbon atoms with a polyalcohol or a glycoside thereof in the presence of a fatty acid soap, at a temperature between 100.degree. and 190.degree.C while simultaneously eliminating water formed during the reaction. The polyalcohol is a linear aliphatic polyalcohol of the formula C.sub.n H.sub.n.sub.+2 (OH).sub.n wherein n is at least 4. Optionally the obtained esters can be further converted. Products are obtained which are useful, for example, as emulsifying agents and baking additives.
