This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.
专利号:US-4161609-A 优先权日:1977-09-14 标题:Synthesis of carboxylic acid esters 发明人:CRAMER RICHARD D 权利人:DU PONT 摘要:A method is provided for converting a carboxylic acid amide to a carboxylic acid ester by reacting a vaporized mixture of the amide and an aliphatic alcohol or a phenol in the presence of a suitable catalyst at temperatures of from 100 DEG C. to 400 DEG C. The process is especially useful for the conversion of methacrylamide to methyl methacrylate.
专利号:US-4665238-A 优先权日:1985-01-22 标题 :Process for the synthesis of alkylaromatic compounds 发明人:IMAI TAMOTSU; BARGER PAUL T 权利人:UOP INC 摘要:Alkylaromatic compounds may be synthesized by reacting an aromatic compound with an alkylating agent comprising a mixture of gases, including carbon monoxide and hydrogen at alkylation conditions in the presence of a dual-function-catalyst. The catalyst system which is employed for this reaction will comprise (1) a composite of oxides of copper and chromium and (2) an aluminosilicate which may be either in crystalline or amorphous form.
