1,200,708. Preparation of phenylesters from benzene. FARBWERKE HOECHST A.G. 21 Aug., 1968 [25 Aug., 1967], No. 40003/68. Addition to 1,185,373. Heading C2C. A process for the catalytic production of phenyl esters from benzene which comprises reacting a mixture of benzene, a saturated aliphatic carboxylic acid and molecular oxygen in the presence of a noble metal of Group VIII of the Periodic Table, the stable valency of which metal in its compounds is at most 4, and at least one element of Group V B or VI B of the Periodic Table, the atomic number of the element being at least 34. The metals of Group V B and VI B are preferably Sb, Bi, Se or Te and may be used in an amount of 60 atom per cent calculated on the noble metal. |
