Abstract
An ester of a polyalkenoxy compound, as herein defined, is prepared by reacting the polyalkenoxy compound with a long-chain saturated fatty acid having at least 8 C atoms, in the presence of hypophosphorous acid, or an alkali metal salt thereof, to form a condensate substantially free of colour. The polyalkenoxy compound is one prepared by the reaction of an alkylene oxide, e.g. ethylene oxide or propylene oxide, with a substance containing a reactive hydrogen atom, e.g. an alcohol or amine. The fatty acid may be lauric or stearic acid. The hypophosphorous acid or equivalent amount of alkali metal salt used preferably amounts to between 0.05% and 2% of the total weight of the reactants. An esterification catalyst may be present. An example is given of the esterification of a condensate of 23 mols. ethylene oxide and one mol. of glycerol, with lauric acid, in the presence of hypophosphorous acid, and p-toluene sulphonic acid.ALSO:An ester of a polyalkenoxy compound, as herein defined, is prepared by reacting the polyalkenoxy compound with a saturated long chain fatty acid having at least 8 carbon atoms, in the presence of hypophosphorous acid, or an alkali metal salt thereof, to form a condensate substantially free of colour.
