METHOD OF PRODUCING ALCOHOLATES OF ALKALI AND ALKALI-EARTH METALS (VERSIONS) Russian patent published in 2014 - IPC C07C29/70 C07C31/30

Abstract RU 2508285 C1

FIELD: chemistry.

SUBSTANCE: described is a method of producing mixed alcoholates of alkali and alkali-earth metals, which involves producing mixed alcoholates containing an alkali metal and an alkali-earth metal in molar ratio of 1:0.05-10, reacting an alkali metal hydroxide with alcohol or a mixture of alcohols, having boiling point under normal conditions higher than 150°C, in a hydrocarbon solvent at temperature of 100-150°C and molar ratio of the alcohol hydroxyl group to the alkali metal hydroxide of 1:0.02-0.6, followed by addition of sodium and an alkali-earth metal.

EFFECT: obtaining a mixed alcoholate, having high effectiveness as a modifier of anionic polymerisation of unsaturated hydrocarbons.
