| titleOfInvention | PROCESS FOR THE MANUFACTURE OF VERY PURE .epsilon.-CAPROLACTONE |
| abstract | ABSTRACT OF THE DISCLOSURE The invention relates to a process for the production of .epsilon.-caprolactone having a purity of 99.9% and increased colour and storage stability which comprises feeding .epsilon.-caprolactone, which has been made by reacting cyclohexanone with a solution of a percarboxylic acid, into a first distillation unit, operating at 0.1 to 500 mbars and drawing off as the top product a mixture consisting of .epsilon.-caprolactone and lower-boiling impurities, feeding the bottom product of said first distillation unit into a second distillation unit, operating at 0.1 to 500 mbars and then drawing off the pure .epsilon.-caprolactone as the top product. The .epsilon.-caprolactone is use-ful as an intermediate for the production of known useful compounds such as polyesterols which are subsequently converted to polyurethanes. |
