LIQUID-PHASE PREPARATION OF DELTA-KETO CARBOXYLIC ACID ESTERS UTILIZING LIQUID-PHASE INSOLUBLE CATALYST Abstract A process is disclosed for making a delta-keto carboxylic acid ester by the addition reaction of a ketone and an acrylic acid ester in the presence ¦ of a catalyst provided by a mixture of a primary amine component and a water- promoted catalytic material component. The water-promoted catalytic material component, which is substantially or entirely insoluble in the reaction medium, is selected from the group of materials consisting of an alkali half- salt of phthalic acid, an aluminum hydrosilicate mineral, a silica-alumina molecular-sieve zeolite, a silica-free alumina and a sulfonated perfluorinated resin. The process is particularly suitable for making methyl 4-oxocaproate from the addition reaction of acetone and methyl acrylate.
