    摘要： Disclosed is a method for preparing a benzyl amine compound, i.e., synthesizing a benzyl amine compound by means of an oxidation reaction between a methylbenzene/ethylbenzene compound and arylamine by using an ionic iron (III) complex containing 1,3-di-tert-butylimidazolium cation and having a molecular formula of [(RNCHCHNR)CH][FeBr4] (R being tert-butyl) and di-t-butyl peroxide as an oxidant. The present invention is not only applicable to a methylbenzene compound containing a benzylic primary carbon-hydrogen bond but also applicable to an ethylbenzene compound containing a benzylic secondary carbon-hydrogen bond, and therefore is widely applicable. This is the first case where the preparation of a benzyl amine compound by means of an oxidation reaction between a methylbenzene/ethylbenzene compound and arylamine is implemented by an iron catalyst.

    摘要： A process for preparing 4-aminodiphenylamine (4-ADPA) comprising steps of coupling of aniline with nitrobenzene in presence of a suitable base, e.g. tetramethylammonium hydroxide (TMAH), hydrogenation of the coupling mass, phase separation, hydrogenation of azobenzene in the separated organic mass and fractional distillation for 4-ADPA recovery. An improvement in 4-ADPA recovery and a lowering of tar formation are obtained due to azobenzene reduction prior to 4-ADPA isolation. Also a gain in volume productivity of 4-ADPA is obtained by suitably altering the batch cycle time of the coupling reaction.

    摘要： A device and method for dissipating heat from a source of heat is described. A plurality of layers of thermally conductive materials receives a flow of heat from a source of heat. A first layer of the plurality of layers receives the flow of heat from the source of heat and redirects and transfers the flow of heat to a second of the plurality of layers. Each layer has a separate preselected thermal impedance to control a desired temperature change across the plurality of layers and to maintain a desired operating temperature of the source heat.
