ABSTRACT OF THE DISCLOSURE Alkanoic acids, esters of such acids, and alkyl nitriles are reacted with formaldehyde in the presence of a basic catalyst comprising pyrogenic silica to form .alpha.,.beta.- unsaturated acids, the esters of such unsaturated acids or .alpha.,.beta.-unsaturated nitriles. The pyrogenic silica is especially effective when treated with activating agents which provide basic sites on the pyrogenic silica catalyst support, such as organic bases, inorganic bases of Group IIA and IIIA metals, and precursors of such bases.
