Title:
MANUFACTURE OF CARBOXYLATE
Document Type and Number:
Japanese Patent JP3818783
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a carboxylate in high yield, with reduced use of catalyst quantity, reducing the deactivation of catalyst, useful as monomer for manufacture of synthetic resin by using a catalyst supporting gold on a carrier.
SOLUTION: The reaction of (A) an aldehyde and (B) an alcohol (methanol or ethanol is preferred) in the presence of the oxygen including gas is carried out in the presence of (C) a catalyst carrying gold. The preferable component (A) is (meth)acrolein and the subject ester is (meth)acrylate or the component (A) is gyloxal and the subject ester is gyloxyl acid ester, and the carrier supporting gold is activated carbon, hydrophobic carrier or a hydrophilic carrier modified into hydrophobic carrier, the reaction is carried out at room temperature to 200°C, under atmospheric pressure to 50 atm., for 1 to 20 hrs.
