PCT No. PCT/EP97/01156 Sec. 371 Date Sep. 15, 1998 Sec. 102(e) Date Sep. 15, 1998 PCT Filed Mar. 7, 1997 PCT Pub. No. WO97/34859 PCT Pub. Date Sep. 25, 1997Proposed is a method of producing alkaline-earth salts of aliphatic beta -keto compounds by reacting alkaline-earth hydroxides with aliphatic beta -ketoesters and/or beta -diketones in the absence of solvent to give the corresponding alkaline-earth salts. The beta -keto compound is added in portions to the powdered alkaline-earth hydroxide and the reaction mixture subsequently dried. Good yields are obtained of a fine-grained, light colored product.
