VERFAHREN ZUR HERSTELLUNG VON CAPROLACTAM |
摘要 |
An improved process for the preparation of caprolactam by heating 6-aminocapronitrile in the presence of a heterogenous catalyst and water under superatmospheric pressure without rapid deactivation of the catalysts used. The process further includes the addition of a low or high boiling alcohol in the heating phase, after which the products are obtained by distillation. The process further includes a method of working up the top and bottom products of the reactors to achieve higher yields. |
