摘要： A process for the liquid phase oxidation of an organic substance-containing effluent which comprises subjecting said effluent to a liquid phase oxidation treatment in the presence of a copper catalyst at a copper ion concentration of 50-5000 ppm and also in presence of an ammonium ion concentration of five or more times the copper ion concentration thereby to oxidize the organic substances in the effluent, and recovering the copper catalyst from the treated effluent for reuse. The recovery of the copper catalyst may be effected either by a process in which the copper catalyst is separated as a precipitate or by a process using a resin adsorption.

摘要： A process for preparing substantially purified aqueous indole solution. In the process of the present invention, crude indole containing an organic impurity is dissolved in an organic solvent which is immiscible with water, the distribution ratio of the impurity to the organic phase, when two-phase liquid system is formed with the organic solvent and an aqueous medium, being greater than that of indole; and the indole solution is contacted with water or an aqueous reaction medium for conducting the reaction to form two-phase liquid system and to distribute indole to the aqueous phase.

摘要： In an industrial process for preparing indole by reacting aniline and ethylene glycol, high boiling-point impurities and non-volatile substances are removed in advance from the reaction mixture either before the recovery of aniline from the reaction mixture or before the subsequent rectification of the resultant indole. Indole of a high purity can thus be obtained.

摘要： Enzyme-containing granules are produced by forming drops of a gellable enzyme-containing liquid with a rotating disc and bringing the drops in contact with a gelling solution. The disc is preferably contained in a column, and the gelling solution flows down walls of the column to a reservoir in a lower legion of the column. Drops of the enzyme-containing liquid from the rotating disc contact the gelling solution while flowing down the walls and are carried to the reservoir. Preferably, the enzyme-containing liquid is an aqueous alginate solution containing the enzyme and the gelling solution is an aqueous calcium chloride solution.

摘要： A process for producing an indole which comprises reacting an aniline and a diol in the presence of a catalyst to produce a reaction mixture containing the indole, unreacted aniline and by-products, condensing the reaction mixture to obtain a liquid reaction product, recovering the unreacted aniline from the liquid reaction product, reducing the contents of specified by-products in the recovered aniline below specified levels and reutilizing the resulting recovered aniline. To reduce the contents of the specified by-products in the recovered aniline below specified levels, it is preferred to subject the liquid reaction product or an aniline fraction separated therefrom to a heat-treatment and then to distillation. In the above manner, the recovered aniline can be reutilized in the reaction without causing the activity of the catalyst to deteriorate.
摘要翻译：一种制备吲哚的方法，其包括在催化剂存在下使苯胺和二醇反应以产生含有吲哚，未反应的苯胺和副产物的反应混合物，将反应混合物冷凝以获得液体反应产物，回收未反应的苯胺从液体反应产物中降低回收苯胺中指定副产物的含量低于指定水平，并再循环回收苯胺。为了将回收苯胺中指定的副产物的含量降低到指定水平以下，优选使液体反应产物或与其分离的苯胺级分进行热处理，然后进行蒸馏。以上述方式，回收的苯胺可以在反应中重新利用，而不会导致催化剂的活性劣化。
