Abstract
PURPOSE: To reduce the concentration and the amount of an inorganic acid used in preparation of pinacolone from a butene and formaldehyde, by adding a salt of the inorganic acid.
CONSTITUTION: Pinacolone is obtained by the reaction of a butene comprising 2-methylbutene-1, 2-methylbutene-2, 3-methylbutene-1, 2-substituted-2-methylbutane of formula I (X=OH, Cl, H2 PO4, etc.), or 3-substituted-2-methylbutane of formula II, or its derivative with formaldehyde in the presence of (A) an aqueous solution of a strong inorganic acid, and (B) a salt of the acid (e.g. CaCl2), which is at least partly soluble in the reaction mixture.
