    摘要： A process for continuously preparing benzophenone-azines comprising oxidizing benzophenone-imines with molecular oxygen or a molecular oxygen-containing gas in the presence of a copper halide catalyst is disclosed. The oxidation reaction is carried out in a multistage system under an oxygen partial pressure gradually decreasing from the former stage to the latter stage and at a conversion gradually decreasing from the former stage to the latter stage, while controlling the conversion so that the molar ratio of the benzophenone-imines to the copper halide in the final stage be maintained at 1 or more. By the process, the continuous reaction can stably be performed at a high conversion of the benzophenone-imines without involving insolubilization and sedimentation of the catalyst.

    摘要： Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites. The benzoyl ring and the phenylhydrazone ring can be substituted with a halogen atom, a nitro group, or an alkyl group of from 1 to 6 carbon atoms, inclusive. A new class of pentahalobenzoyl chloride phenylhydrazones is described, particularly pentafluorobenzoyl chloride phenylhydrazones. A further new class of alkylbenzoyl chloride phenylhydrazones, particularly p-toluoyl chloride phenylhydrazones are also described. The compounds are prepared by reacting a benzoic acid phenylhydrazide with phosphorus pentachloride to obtain a benzoyl chloride (dichlorophosphinyl)phenylhydrazone that is reacted with phenol to produce the desired benzoyl chloride phenylhydrazones. Certain of the compounds can be prepared by direct chlorination of a benzaldehyde phenylhydrazone. Methods of use and compositions are described.
