Tri-acylates of lanthanum and cerium(III) are quantitatively precipitated by the reaction of their nitrates or chlorides with excess of sodium soaps (laurate, palmitate, stearate) in aqueous solutions. These salts are not hydrolysed by water and are soluble in hot benzene from which pure samples may be crystallized. Molecular weight measurements show them to be monomeric in benzene. Viscosities of
