Abstract

1397039 Methyl vinyl ketone F HOFFMANN-LA ROCHE & CO AG 9 Oct 1973 [10 Oct 1972] 47085/73 Heading C2C Methyl vinyl ketone is prepared by reacting formaldehyde with acetone in the presence of a strong acid in the liquid phase, substantially free of a solid or gaseous phase. Organic or inorganic acids may be used. A diluent may be present, e.g. water or methanol. 3 Keto-butan- 1-ol may be a by-product.
