    CPC classification number: C07F9/02

    Abstract: This invention concerns the use of homogeneous ruthenium and iron catalyst complexes preferably stabilized by a displaceable ligand such as triphenyl phosphine, and/or solubilized by a solvating agent such as the lower alkanols, said catalyst complexes being utilized as reducing agents in the presence of a non-aqueous, non-oxidizing reaction medium, at reaction temperatures of from about 35* to 160* C and under superatmospheric pressures of at least 100 psig, in a substantially hydrogen atmosphere, to selectively reduce at least one nitro group of nitroaromatics to the corresponding aromatic amine.

    Abstract translation: 本发明涉及使用均匀的钌和铁催化剂配合物，优选通过位移配体例如三苯基膦稳定，和/或通过溶剂化物如低级链烷醇溶解，所述催化剂配合物用作还原剂，在 非水，非氧化反应介质，在大约35°至160℃的反应温度和至少100psig的超大气压下，在基本氢气氛中，选择性地将至少一个硝基芳族硝基还原成 相应的芳香胺。

    CPC classification number: C07C209/48

    Abstract: THIS INVENTION RELATES TO A PROCESS FOR REDUCING NITROPARAFFINICS CONTAINING 3 TO 20 CARBON ATOMS BY HEATING SAID NITROPARAFFINS AT REACTION TEMPERATURES RANGING FROM 35* C. TO 150* C., IN A HIGHLY ALKALINE, SUBSTANTIALLY NON-AQUEOUS REACTION MEDIUM WITH A RUTHENIUM OR IRON HOMOGENEOUS CATALYST, IN A SUBSTANTIALLY HYDROGEN ATMOSPHERE AT SUPERATMOSPHERIC PRESSURED OF AT LEAST 100 P.S.I.G. AND CONTINUING HEATING SAID REACTION MIXTURES UNTIL THE NITROPARAFFINS ARE REDUCED TO THE CORRESPONDING AMINES.
