Catalyst for the preparation of carboxylic esters and method for producing carboxylic esters
摘要：
It is an object of the present invention to provide a catalyst for manufacturing a carboxylic ester, which has superior catalytic activity. The present invention relates to a catalyst for preparing a carboxylic ester, used in a) a reaction for preparing a carboxylic ester by reacting oxygen, an aldehyde, and an alcohol, or b) a reaction for manufacturing a carboxylic ester by reacting oxygen and one or more types of alcohol, comprising a carrier and 1) ultrafine gold particles and/or 2) ultrafine metal particles containing gold and a second element other than gold, having an average particle diameter of not more than 6 nm, are supported on the carrier.
摘要（中）：
