Abstract:
A method for producing α-, β-unsaturated carboxylic acid esters in high yield from reaction by-product streams via the catalytic conversion of the by-products to additional α-, β-unsaturated carboxylic acid ester product. The catalyst comprises cesium, and phosphorous as a promoter, on a porous support.
