Abstract: This invention relates to a process for the production of lactams by catalytic rearrangement of cycloketoximes in the presence of oleum. More specifically the invention relates to improving yields of lactam while reducing undesirable by-product formation by use of three stages of rearrangement with correlated adjustment of reaction conditions in each stage. Critical variables in each stage include acid concentration, free SO3 concentration, percent oxime added, reaction temperature and extent of mixing. Normally, the oxime fed to the process contains up to 6 percent water.
Abstract translation: 本发明涉及在发烟硫酸存在下通过环酮肟催化重排生产内酰胺的方法。 更具体地,本发明涉及通过使用三个阶段的重排与各阶段中的反应条件的相关调整来提高内酰胺的产率,同时减少不期望的副产物形成。 每个阶段的关键变量包括酸浓度,游离SO3浓度,加入的肟百分比,反应温度和混合程度。 通常,喂给该方法的肟含有高达6%的水。
