Abstract
Disclosed are processes for the manunfacture of 3,4-epoxy-1-butene (EpB) and, particularly, for the recovery of EpB from an epoxidation effluent comprising EpB, butadiene, oxygen and an inert gas obtained by the selective epoxidation of butadiene with an oxygen-containing gas in the presence of a catalyst and an inert gas. EpB is separated from the effluent by means of an absorption process using liquid butadiene as the absorbent material.
