Reaction Steps

Into a pressure vessel equipped with magnetic agitation is placed a liquid charge of 92% p-xylene and 4.0% each of p-methyl benzyl alcohol and p-tolualdehyde which are obtainable from recycling streams and is then pressurized with 45 p.s.i.a. oxygen and then pressurized with ethylene. The reaction mixture is heated to 190° C. and reacted for 30 min. with agitation at a system pressure of 1420 p.s.i.g. The liquid phase effluent is found to contain 1.52% ethylene oxide, 4.5% p-methyl benzyl alcohol and 4.4% p-tolualdehyde. The amount of p-toluic acid formed was not determined.
