Abstract
A process for the industrial production of ethylene oxide and an aromatic acid by reacting oxygen with ethylene and a methyl aromatic compound in the liquid phase. Oxygen and ethylene are passed into a liquid mono or poly methyl aromatic compound and reacted therein to produce ethylene oxide and methyl aromatic oxidates. The aromatic oxidates are then further oxidized to produce aromatic acids. When the methyl aromatic compound used is toluene the acid produced is benzoic acid, from p-xylene, terephthalic acid is produced; from m-xylene isophthalic acid is produced; and from pseudocumene (1, 2, 4 trimethyl benzene) trimellitic acid is produced.
