<p>An oxidation process for the manufacture of higher aryl esters characterised by reacting a mixture of a higher aromatic hydrocarbon, an organic solvent, a carboxylic acid of the formula R(COOH)n wherein n is an integer of from 1 to 2 and R is a hydrocarbon group having at least 5-n carbon atoms and molecular oxygen in the liquid phase at a temperature in the range of from 100 to 300 deg.C with a catalyst composed of palladium or a compound of palladium, an antimony compound and a compound of at least one member selected from the group consisting of alkali metals and alkaline earth metals wherein water formed in the oxidation reaction is continuously removed from the reaction mixture by continuous distillation of some of the organic solvent from the reaction mixture. - (6pp) EPAB- EP-163748 B An oxidation process for the manufacture of higher aryl esters characterised by reacting a mixture of a higher aromatic hydrocarbon, an organic solvent, a carboxylic acid of the formula R(COOH)n wherein n is an integer of from 1 to 2 and R is a hydrocarbon group having at least 5-n carbon atoms and molecular oxygen in the liquid phase at a temperature in the range of from 100 to 300 deg.C with a catalyst composed of palladium or a compound of palladium, an antimony compound and a compound of at least one member selected from the group consisting of alkali metals and alkaline earth metals wherein water formed in the oxidation reaction is continuously removed from the reaction mixture by continuous distillation of some of the organic solvent from the reaction mixture. USAB- US4477385 A Process comprises oxidising naphthalene, anthracene, biphenyl plenanthrene, fluorene or terphenyls in an organic solvent with a carboxylic acid R(COOH)n where n is 1 or 2 (1) and R is a hydrocarbon gp. with at least 5-n (7-11)C and mol. 0 in the liq. phase at 100-300 deg.C in the presence of carboxylate of Pd, Sb and an alkali or alkaline earth (K, Cs, Na, Li or Zn). - The solvent may be a linear CnH2n+2 or cyclic CnH2n hydrocarbon whose n is 4-14 or ether. Water formed in the reaction may be removed by continuous distn. of solvent.</p> |
