Abstract

A method of producing an ethylenically unsaturated, typically, an α, β ethylenically unsaturated carboxylic acid or ester is described. The method comprises the steps of contacting formaldehyde, or a source of formaldehyde, with a carboxylic acid or ester in the presence of a catalyst and optionally in the presence of an alcohol. The catalyst comprises barium phosphate leaf or plate shaped/like crystals, or a source thereof. A catalyst system is also described. The catalyst system comprises a crystalline barium phosphate catalyst and optionally a catalyst support.
