Title (EN) A METHOD OF MINIMIZING ALDEHYDE-BASED IMPURITIES IN A PROCESS STREAM
(FR) PROCEDE PERMETTANT DE REDUIRE LES IMPURETES A BASE D'ALDEHYDES DANS UN FLUX DE TRAITEMENT
Abstract: front page image
(EN)Oxidation of an alkane to an alkanone in a process stream forms aldehyde-based impurities. A method of minimizing the aldehyde-based impurities introduces an amine into the process stream to minimize the aldehyde-based impurities. The amine interacts with the alkanone and the aldehyde-based impurities thereby forming heavy products. The method separates the heavy products from the alkanones to reduce a level of the aldehyde-based impurities. The process stream preferably includes cyclohexyl ketone as the alkanone and n-hexanal as the aldehyde-based impurity. The method is typically involved in synthesis of a caprolactam.
(FR)L'oxydation d'un alcane en alcanone dans un flux de traitement entraîne la formation d'impuretés à base d'aldéhydes. L'invention concerne un procédé permettant de réduire les impuretés à base d'aldéhydes, consistant à introduire une amine dans le flux de traitement a fin de réduire les impuretés à base d'aldéhydes. L'amine interagit avec l'alcanone et les impuretés à base d'aldéhydes, de manière à former des produits lourds. Le procédé consiste à séparer les produits lourds des alcanones afin de réduire le taux d'impuretés à base d'aldéhydes. L'alcanone contenue dans le flux de traitement est de préférence du cyclohexylcétone, et l'impureté à base d'aldéhyde du n-hexanal. Ce procédé convient en particulier pour la synthèse d'un caprolactame.
