Abstract: PROBLEM TO BE SOLVED: To provide a new method for separating a mixture containing an amide compound and an acid in order to solve problems that a large amount of a counterion or a base as a third component is required when an attempt to separate the amide compound from the acid is made and a large amount of products neutralized with the base is produced. SOLUTION: An adsorbent satisfying a/b

Abstract: PROBLEM TO BE SOLVED: To directly obtain a lactam without causing formation of ammonium sulfate as a by-product and without separating an oxime by carrying out the synthesis of the lactam from a cycloalkane as a starting raw material using a solvent except the cycloalkane in the absence of sulfuric acid. SOLUTION: A mixture of (A) a perhalogenated nitrosoalkane (preferably trichloronitrosomethane) and (B) a cycloalkane (preferably cyclohexane or cyclododecane) is irradiated with light rays in the absence of sulfuric acid in an organic solvent (preferably chloroform) to give a lactam. Trichloronitrosomethane obtained by photonitrosation of nitrosyl chloride and chloroform is preferable as the component A. The light irradiation is preferably carried out under reduced pressure or normal pressure at 0-30 deg.C by light at 400-600 nm. Consequently, the rearrangement can be carried out without separating a cycloalkanone oxide of intermediate to give directly the lactam.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing trichloronitrosomethane by which the compound is produced while reducing the required amount of nitrosyl chloride, and the removal of the remaining nitrosyl chloride after stopping the reaction is facilitated by carrying out the stirring of a liquid during the irradiation of light by using a specific method when carrying out the photoreaction of the nitrosyl chloride with chloroform. SOLUTION: The stirring of a liquid during the irradiation of light is carried out by the stirring by the blowing or jetting of an inert gas when carrying out the photonitrosation of (A) nitrosyl chloride with (B) chloroform to provide the objective trichloronitrosomethane. The reaction is carried out by dissolving the component A in the component B having combined two roles of the reagent and the solvent, and irradiating the obtained solution with the light of 400-600 nm, preferably 500-600 nm at 0-30 deg.C preferably under a normal pressure. The amount of the component A dissolved in the component B is preferably 0.5-30 g/L, more preferably 5-15 g/L. The inert gas includes a gas inert to the reaction of the components A and B (e.g. hydrogen chloride gas) besides the inert gas such as nitrogen.
