    Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing an amide or a lactam at a high yield by causing the rearrangement reaction of an oxime compound to proceed, without generating a large amount of byproducts such as ammonium sulfate. SOLUTION: The method for producing an amide or a lactam comprises subjecting an oxime compound to a rearrangement reaction in the presence of a compound comprising a structure represented by the following formula (1)-Z-X (1) (in the formula, Z represents a P atom, an N atom, an S atom, a B atom or an Si atom, and X represents a leaving group, provided that Z is bound to one or two or more atom(s) or group(s) in addition to X) to form a corresponding amide or a corresponding lactam. In the production method, X may be a halogen atom. COPYRIGHT: (C)2010,JPO&INPIT

    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.
