    摘要: A process for preparing 1-aminoanthraquinone having high purity, which comprises either1. hydrogenating 1-nitroanthraquinone in an aqueous medium in the presence of a base using a hydrogenating catalyst, and then oxidizing the hydrogenation product, or2. hydrogenating crude 1-nitroanthraquinone containing dinitroanthraquinones as impurities or crude 1-aminoanthraquinone containing diaminoanthraquinones as impurities in an aqueous medium in the presence of a base using a hydrogenating catalyst, stopping the hydrogenation at a time when the 1-nitroanthraquinone or 1-aminoanthraquinone has been substantially reduced to 1-aminoanthrahydroquinone but the dinitroanthraquinones or diaminoanthraquinones remain substantially unreduced to diaminoanthrahydroquinones, removing water-insoluble materials from the reaction mixture, and then oxidizing the remaining water-soluble residue.

    摘要: Aromatic urethanes are produced by interacting an aromatic nitro compound, an organic compound containing hydroxyl groups and carbon monoxide in the presence of a catalyst composed of elemental selenium or a selenium compound and of a promoter composed of a bicyclic amidine together with a phenolic compound or a carboxylic acid. The interaction proceeds smoothly with the aid of a small amount of the promoter, attended with secondary production of amino compounds only in small amounts. For instance, 2,4-diethyldicarbamatetoluene is obtained at a yield of 87% by interacting 2,4-dinitrotoluene, ethanol and carbon monoxide in the presence of a catalytic system composed of metallic selenium, 1,8-diazabicyclo(5,4,0)-undecene-7 and acetic acid.

    摘要: Aromatic urethanes can be produced in exceedingly improved yield when an aromatic nitro compound, an organic compound containing hydroxyl groups, and carbon monoxide are reacted in the presence of a catalyst composed of metallic (elemental) selenium or a selenium compound and a base serving as promoter, to which reaction system an aromatic amino compound and/or an aromatic urea compound which will be secondarily produced by the reaction has been previously added in order to suppress side reactions. For instance, when nitrobenzene, methanol and carbon monoxide are interacted in the presence of metallic selenium and triethylenediamine, the conversion of nitrobenzene is 68% and the percentage of formed methyl N-phenylcarbamate to the interacted nitrobenzene is 80%, whereas when the reaction is effected under the same reaction conditions indicated above with addition to the reaction system of aniline in an amount of about 15 wt. % of the nitrobenzene, the conversion of nitrobenzene and the percentage of formed methyl N-phenylcarbamate reach 100% and 98%, respectively.

    摘要: An aromatic urethane of high quality and excellent heat stability can be produced in high yield by reacting an aromatic nitro compound, a hydroxyl group-containing organic compound and carbon monoxide in the presence of a catalytic system composed of (1) palladium, ruthenium, rhodium or a compound thereof, (2) a Lewis acid, and (3) ammonia. The use of such catalytic system can suppress undesirable side reactions to a satisfactory extent and ensures the reaction to proceed without causing any corrosion of a stainless steel reactor. If necessary, water may be added to the reaction system to increase the reaction velocity, by which the unit cost of the catalyst can be reduced.

    摘要: A method for the preparation of a halogenated aromatic amine, wherein a halogenated aromatic nitro compound is hydrogenated in liquid phase in the presence of a platinum-base catalyst to obtain a corresponding halogenated aromatic amine, the hydrogenation being carried out in the presence of an alkylmonoamine, an alicyclic amine or a polyalkylenepolyamine. The presence of the amine well suppresses a dehalogenation reaction which would otherwise be involved, so that not only a high purity halogenated aromatic amine is obtained, but also corrosion of a reactor is prevented.
