    摘要: Described are processes for the preparation of diphenylamine or a nucleus-substituted derivative thereof, which comprise, upon feeding into a reaction system a phenol compound and reacting in the reaction system a cyclohexanone compound with an aniline compound in the presence of a hydrogen transfer catalyst and a catalytic amount of the cyclohexanone compound corresponding to the phenol compound while using the phenol compound as a hydrogen acceptor and forming the cyclohexanone compound in the reaction system, employing a hydroxide, carbonate or bicarbonate of an alkali metal and/or an alkaline earth metal when the hydrogen transfer catalyst is one of noble metals of Group VIII of the periodic table, respectively.

    摘要: An internal release agent comprises a sulfur-containing acid phosphoric esters selected from the group consisting of thiophosphoric acid esters and dithiophosphoric acid esters of the formula,

    where X and Y are independently selected from the group consisting of an oxygen atom and a sulfur atom, at least one of X and Y is a sulfur atom, and R₁ and R₂ are independently alkyl groups.
