    Abstract: The present invention relates to a method for producing a high purity, high quality amide compound, particularly, lactam. A first embodiment of the present invention is characterized in that an amount of each of a halide, an aldehyde compound, an alcohol compound and a nitrile compound contained in a solution recycled into an oxime-forming step is controlled to an amount of 0.4 mol % or less based on the ketone as a starting material. A second embodiment of the present invention is characterized in that one or more compounds selected from the group consisting of a ketone, an oxime and an amide compound are purified by hydrogenation and/or crystallization for eliminating impurities containing a double bond. A third embodiment of the present invention is characterized in that a content of impurities having a cyclic bridge structure is controlled by using a cycloalkanone purified by recrystallization.

    Abstract: A process is provided for producing null-caprolactam from cyclohexanone oxime. The process comprises a evaporation step of a mixture of cyclohexanone oxime and a solvent by introducing the mixture into a fluidized bed in which inert particles is fluidized by an inert gas, the particles having heat enough to evaporate the mixture; and a rearrangement step of cyclohexanone oxime in the evaporated mixture into null-caprolactam by a gas phase Beckmann rearrangement reaction using a solid catalyst, excluding a catalyst consisting of a boric acid or a boron oxide.

    Abstract: Disclosed is a method for selectively deactivating catalytically active sites which occur only on the surface of a zeolite of boralite catalyst. Active sites occurring on the interior of the pores are masked by saturating the catalyst with an organic compound which fills substantially the whole of the catalyst pore volume. The catalyst so treated is then exposed to a deactivating agent, such as a solution of an alkali metal salt which is substantially immiscible with, substantially insoluble in, and which is otherwise unreactive to said pore-filling compound. The catalyst is then treated to drive off the pore-filling compound, yielding a catalyst selectively deactivated only on the external surface, but which is not deactivated within the pores. The treatment enables the catalyst to be used for e.g. hydrocarbon conversion for long time periods without carbon buildups around the pore entrances, which buildup would otherwise either restrict entry into the pores by reactants or exit therefrom by product.
