摘要：
Disclosed is a process of recovering 3,4-epoxy-1-butene (epoxybutene) from an epoxybutene-laden reaction product gas by absorption into a high-boiling solvent. Also disclosed is a process for the purification of the epoxybutene by separating epoxybutene from the solvent and other reaction by-products by a novel combination of distillation and decantation steps.
