Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

B01D 334

US Classification:

203 43, 203 49, 203 63, 203 64, 203 59, 203 60, 203 62, 203 67, 203 68, 203 69, 203 70, 203 75, 203 77, 203 80, 203 78, 568366

Abstract:

A process for the recovery and purification of cyclobutanone from a crude product mixture obtained from an oxidation product mixture resulting from the oxidation of cyclobutanol to cyclobutanone in the presence of water. The process provides for the recovery of cyclobutanone in a purity of at least 90 weight percent by a combination of distillation steps.

International Classification:

C07D31500

US Classification:

549507

Abstract:

Disclosed is a process for the continuous production and recovery of 2,3-dihydrofuran (2,3-DHF) by the isomerization of 2,5-dihydrofuran (2,5-DHF) which contains certain impurities to 2,3-dihydrofuran in yields exceeding 95%. The process utilizes, in order, an isomerization zone containing one or more beds of a supported, palladium or platinum catalyst, a product recovery zone comprising a distillation column, a high boiler removal zone and means for feeding the 2,5-DHF component of the bottoms stream from the product recovery zone to the isomerization zone.

International Classification:

C07D30110
C07D30304

US Classification:

549536

Abstract:

Disclosed herein is an improved gas phase process for the selective epoxidation of non-allylic olefins wherein the epoxidation is carried out in the presence of certain inert, paraffin hydrocarbons. Such hydrocarbons possess higher heat capacities as compared to other materials, e. g. , nitrogen, argon, methane and helium, typically used as inert diluents in olefin epoxidations. The disclosed process is particularly useful for the continuous manufacture of 3,4-epoxy-1-butene from 1,3-butadiene.
