ABSTRACT:
A process for recovering 3,4-epoxy-1-butene from a vapor phase catalytic oxidation reactor effluent where 1,3-butadiene is reacted with oxygen over a silver catalyst, the process includes the steps of contacting the reactor effluent with an absorbent in an absorber and vaporizing in the absorber an effective amount of a non-reactive coolant to cool the absorber to a temperature of less than about 40.degree. C. and a pressure of less than about 4 bar. Advantageously, the vaporization of the non-reactive coolant proximate to the absorber allows the absorber to be operated at lower temperatures and pressures than heretofore possible and provides a further advantage of allowing higher O.sub.2 concentrations in the feed to the epoxidation reactor.
