FIELD: industrial organic synthesis.
SUBSTANCE: tert-butylacetone is prepared by cleavage of hydrochloric acid from pinacolin-phosphorus pentachloride reaction products obtained in presence of alkali metal alcoholate. Reaction is conducted in high-boiling indifferent solvent, in particular hydrocarbons boiling above 120оС. Alcoholates can be selected from sodium and potassium butylate and amylate (with linear and branched structures).
EFFECT: increased yield of desired product, simplified process, and widened base of starting material including such an inexpensive reagent as phosphorus trichloride.
