Abstract

L'invention concerne un procédé d'épuration de mélanges qui contiennent un cyclo-alcanone avec 5-12 atomes de carbone dans l'anneau et qui sont obtenus par l'oxydation du cyclo-alcane correspondant en phase liquide, à l'aide d'un gaz contenant de l'oxygène moléculaire. Conformément à l'invention, on soumet le mélange contenant de la cyclo-alcanone à une réaction de condensation d'aldol, dans laquelle on convertit au moins 80 % des aldéhydes présentes, mais qu'on saponifie tout au plus 20 % des esters de cyclo-alcoyle qui sont déduits d'acides carboxyliques possédant au moins 4 atomes de carbone par molécule. On fait se convertir alors de préférence tout au plus 0,2 % de la cyclo-alcanone de plus qu'il soit nécessaire pour enlever des aldéhydes. La cyclo-alcanone libérée ainsi des aldéhydes peut être traitée en un polylactame ayant une résistance mécanique extrêmement élevee.The invention relates to a process for the purification of mixtures which contain a cyclo-alkanone with 5-12 carbon atoms in the ring and which are obtained by the oxidation of the corresponding cyclo-alkane in the liquid phase, using 'a gas containing molecular oxygen. In accordance with the invention, the mixture containing the cycloalkanone is subjected to an aldol condensation reaction, in which at least 80% of the aldehydes present are converted, but at most 20% of the esters of cyclo-alkyl which are derived from carboxylic acids having at least 4 carbon atoms per molecule. At most 0.2% more of the cycloalkanone is then converted preferably more than is necessary to remove aldehydes. The cycloalkanone thus liberated from the aldehydes can be processed into a polylactam having extremely high mechanical strength.
