METHOD OF PRODUCING POTASSIUM METHYLATE Russian patent published in 2009 - IPC C07C31/30 C07C29/70 

FIELD: chemistry.

SUBSTANCE: potassium methylate in form of dry substance or anhydrous solution in methyl alcohol is used as a catalyst when splitting oils and fats, in etherification reactions during production of biodiesel, surface active substances, pharmaceutical and cosmetic preparations. The method involves reacting potassium hydroxide and methanol at high temperature with removal of the formed water using dry methyl alcohol. Synthesis is done in a reaction-separation process in a film type counterflow column reactor at 92-130°C, uniform on the entire height of the reactor, while feeding the initial solution from the top, made by dissolving potassium hydroxide in methyl alcohol, and dry methyl alcohol vapour from the bottom.

EFFECT: more efficient desorption of the formed water and output of the process and reduced energy consumption of the process.
