Recovery and purification of 3,4-epoxy-1-butene using water-miscible solvents |
摘要 |
Disclosed is a method of recovering and purifying 3,4-epoxy-1-butene (epoxybutene) from an epoxidation effluent gas obtained by the vapor phase, catalytic, partial oxidation of 1,3-butadiene (butadiene) with molecular oxygen in the presence of a silver catalyst wherein the epoxybutene-laden epoxidation product gas is reacted with a water-miscible solvent to absorb the epoxybutene. The disclosed process includes a method of separating epoxybutene from the solvent and other reaction by-products by a novel combination of distillation and decantation steps.
