    摘要： A process has been developed for the depyrophorization of pyrophoric metal catalysts, such as Raney nickel catalysts, which comprises treating said pyrophoric metal catalysts in water and/or an organic solvent with an organic nitro compound or a nitroso compound. The catalysts which are obtained according to the process of the invention are useful for carrying out all hydrogenation reaction which can be carried out using the corresponding pyrophoric catalysts. The catalysts obtained are further distinguished by high activity and extended life. They are not contaminated by contact catalyst poisons and can be used essentially without pre-activation.

    摘要： A process for the tertiary dealkylation of a tertiary alkyl containing m- and/or p-cresol wherein a tertiary alkyl containing m- and/or p-cresol is continously introduced into a reaction vessel with a small amount of sulfuric acid or an quivalent amount of a sulfonic acid and the reaction vessel contains a high concentration of m- and/or p-cresol or a high boiling phenol which under the prevailing reaction conditions is not substantially vaporized from the reaction mixture. The reaction mixture is maintained at a temperature of no greater than 230.degree. C. The reaction products are withdrawn continuously from the reactor (and separated into its components) and at the same time a small amount of the reaction mixture being withdrawn intermittently or continously from the reactor.

    摘要： A process for the removal of acids and potential acid-forming agents from a composition containing such acids and potential acid-forming agents and an alkylphenol which composition is obtained by reacting phenols with alkenes in the presence of sulfuric acid or a sulfonic acid, and for treating the effluent thereby obtained, the process being characterized by the steps of:(a) extracting a major amount of the acid constituents from the alkylphenol mixture by means of water;(b) treating the alkylphenol mixture with a dilute aqueous alkali solution in an amount such that the alkali is insufficient to neutralize all the acid originally present in the alkylphenol mixture,(c) separating the alkylphenol mixture from the aqueous alkali solution;(d) combining the aqueous phases obtained from steps (a) and (b);(e) heating the combined aqueous phases to a temperature of 100.degree. to 200.degree. C,(f) separating off the organic phase obtained in step (e); and(g) discharging the aqueous phase.

    摘要： A process for the continuous preparation of a ditertiary butylcresol wherein m- or p-cresol is reacted with isobutene at elevated temperature using H.sub.2 SO.sub.4 as catalyst wherein the process is carried out stepwise by introducing stepwise into a reaction mixture comprising substantially all of the cresol to be reacted with isobutene. The total amount of isobutene introduced is introduced such that less isobutene is charged in a last stage of the process than in the first stage thereof. Thereafter the catalyst is deactivated.
