Abstract
PURPOSE: To obtain a highly efficient oil-water separating agent, by adding ethylene oxide to a polyhydric alcohol having a specified structure in the presence of a catalyst, and esterifying part of the terminal hydroxyl groups with a fatty acid.
CONSTITUTION: An oil-water separating agent is composed of a compound, represented by the general formula, having an HLB value of 11W15. The oil-water separating agent having said composition is prepared as follows: ethylene oxide is added to a polyhydric alcohol, e.g. glycerol, tetritol, pentitol or sorbitol, in the presence of an acid or alkali catalyst, and then part of the terminal hydroxyl groups is esterified with a fatty acid so that a product includes at least one intact hydroxyl group. The fatty acid to be used includes one having 8W22 carbon atoms, e.g. lauric, stearic, tallow or coconut fatty acid. The obtained oil- water separating agent is added, as such or diluted with an organic solvent, e.g. toluene, to a crude oil emulsion at a rate of 0.001W0.05wt% in general.
