| titleOfInvention | Process for the purification of cycloalkanone mixtures obtained in the oxidation of cycloalkanes |
| abstract | ABSTRACT OF THE DISCLOSURE Aldehydes are removed by aldol condensation from a mixture containing a C5-C12 ring atom cycloalkanone, aldehydes and corresponding cycloalkyl esters of C4 or greater carboxylic acids, the mix-ture resulting from the liquid phase oxidation of the corresponding cycloalkane with molecular oxygen. The aldol condensation reaction converts at least 80% of the aldehydes present while no more than 20% of the cycloalkyl esters are saponified. A slight excess of no more than 2% of the cycloalkanone required for the aldehyde removal is converted in the aldol condensa-tion. Cycloalkanones thus treated and freed of the aldehyde are processed into polylactams exhibiting particularly high mechanical strengths. |
