Abstract

Proposed 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.
