Process for preparing gamma-caprolactone by isomerization of epsilon-caprolactone |
| abstract |
A process for preparing gamma-caprolactone comprising isomerizing epsilon-caprolactone in an aqueous medium in the presence of catalytically effective amounts of hydriodic acid or hydrobromic acid wherein the catalyst is optionally promoted with a Group VIII metal. The temperature for the reaction is in the range of about 175° C. to about 250° C. and the ratio of water to epsilon-caprolactone is at least about 1:1. |
