A process for the manufacture of water soluble higher fatty monoglyceride monosulfate detergents is described which includes reacting a sulfating agent, such as chlorosulfuric acid, with glycerol dissolved in an organic solvent, such as chloroform, to trisulfate the glycerol, reacting the glycerol trisulfuric acid made with a higher fatty acid or a higher fatty acid methyl ester in such a solvent, extracting the reaction mixture with a solvent for the monoglyceride disulfuric acid, such as aqueous lower alkanol, and neutralizing the extracted monoglyceride disulfuric acid with an aqueous neutralizing agent to make the water soluble detergent salt. Among preferable detergent salts made are sodium hydrogenated coco fatty monoglyceride sulfate, sodium hydrogenated palm kernel fatty monoglyceride sulfate, sodium hydrogenated palm fatty monoglyceride sulfate, sodium hydrogenated tallow fatty monoglyceride sulfate, and mixtures of two or more thereof. In modifications of the processes the extraction and neutralization operations are effected simultaneously, preferably with a slurry of sodium bicarbonate, as neutralizing agent, in aqueous lower alkanol. The products resulting are of improved quality and of higher detergent content and the processes are more efficient, requiring only stoichiometric amounts of reagents, reducing formation of sodium sulfate and improving the yields of detergent, compared to similar prior art products and processes for the production thereof.
