摘要： Preparation process of indole from aniline and ethylene glycol. Upon preparing indole by reacting aniline and ethylene glycol in a gas phase and in the presence of a catalyst, ethylene glycol is charged in portions to a multiplicity of catalyst stages formed by dividing a catalyst bed and connected in series. This divided supply of ethylene glycol permits the suppresing of the decomposition of ethylene glycol, even if the molar ratio of feed aniline to total feed ethylene glycol is small. The above process permits making the yield of indole large and reducing the amount of unreacted aniline to be separated and recovered from the reaction effluent.

摘要： A process is provided for the preparation of an indole from aniline or a derivative thereof and a polyhydric alcohol. The reaction is carried out in the presence of a catalyst composed of a carrier having a specific surface area of at least 10 m.sup.2 /g and silver supported on the carrier. The catalyst also contains as an additional component a specific amount of at least one element selected from Co, Fe and Ni. Deterioration in catalytic performance of the catalyst during the reaction and its regeneration are therefore minimized.

摘要： In a process for preparing an indole by reacting an aniline with a diol, a catalyst the activity of which has been reduced through its use in the reaction is brought into contact with an inert gas containing 5 vol. % or less of oxygen so that the catalyst is regenerated for its repeated utilization. The activity of the regenerated catalyst is enhanced further when it is subjected to a reducing treatment for activation upon its reutilization.

摘要： An aqueous solution of acrylamide obtained by catalytic hydration of acrylonitrile in the presence of a copper-based catalyst is purified by the steps, in sequence, of (a) removal of the unreacted acrylonitrile, (b) removal of copper, (c) treatment under basic conditions, (d) cation exchanging treatment and (e) weakly basic anion exchanging treatment. The acrylamide obtained by this process has good storage stability. An acrylamide polymer produced from this monomer is useful as a flocculant having a reduced content of the unreacted monomer, a high molecular weight and excellent solubility in water.
