ABSTRACT:
Unsaturated ketones are produced from ketones and paraformadehyde under mild reaction conditions utilizing a catalyst comprising a halogen acid salt of a secondary amine and a nonsoluble solid oxide of an element selected from groups IB, IIIA, IVA, IVB, VA, VB, VIB and VIII of the periodic table. Temperatures of 120-150 and pressures of 700-1200 kpa are preferred; by-products may include di-unsaturated ketones such as divinyl ketone. Unsaturated ketones such as methyl vinyl ketone are useful in imparting ultraviolet sensitivity to plastics which enhances degradability.
