<p>1,167,258. Carboxylic acid esters of aromatic hydroxy compounds. GULF RESEARCH & DEVELOPMENT CO. 14 Dec., 1967 [19 Dec., 1966], No. 56803/67. Heading C2C. Carboxylic acid esters of aromatic hydroxy compounds including a heterocyclic aromatic compound, wherein said hydroxy group is on the aromatic nucleus are obtained by heating an aromatic compound with a catalyst selected from Fe, a noble metal or compounds of these metals, in the presence of NO 3 - ions or species convertible to nitrate ions and a carboxylic acid. Examples are given for the production of phenyl acetate,α- and #-naphthyl acetate, o- and p-chlorophenyl acetate, methyl m- or p-acetoxy-benzoate, o-, m- and p-tolyl acetate and phenyl propionate.</p> |
