Process for the production of pure carboxylic acid-1-monoglycerides

In a process for the product of a very pure carboxylic acid-1-monoglyceride comprising reacting a carboxylic acid having 7 to 20 carbon atoms with glycidol at 80.degree. to 200.degree. C. in the presence of a basic reacting alkali metal or alkaline earth metal compound as a catalyst the improvement comprising conducting said reaction in an inert solvent which forms a homogeneous solution with reactants at said temperature said solvent being selected from the group consisting of an aromatic hydrocarbon, a halogenated benzene, a halogenated toluene, an aliphatic ketone having 3 to 9 carbon atoms and an aliphatic ether having at least 6 carbon atoms.
