LIQUID PHASE MANUFACTURE OF DELTA-KETOCARBOXYLIC ACID ESTER WITH LIQUID PHASE-INSOLUBLE CATALYST
Document Type and Number:
Japanese Patent JPS58194840
Kind Code:
A
Abstract:
LIQUID-PHASE PREPARATION OF DELTA-KETO CARBOXYLIC ACID ESTERS UTILIZING LIQUID-PHASE INSOLUBLE CATALYST 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 waterpromoted 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 halfsalt 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.
