Method of minimizing aldehyde-based impurities in a process stream |
| abstract |
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. |
