Abstract
A process for preparing alkaliacetylacetonates from acetylacetone and alkali hydroxide, which consists of slowly adding an aqueous alkali hydroxide solution to an at least stoichiometric amount of acetylacetone dissolved in acetone, while stirring; dissipating the generated reaction heat by cooling, separating the precipitated alkaliacetylacetonates formed in the reaction, rinsing with acetone, and drying. The products of the reaction may be used in a large number of addition and condensation reactions as one of the reagents, and are sometimes effective as catalysts.
