Abstract
Метод за получаване на производни на р-аминодифениламина от р-нитродифениламин или от р-нитрозодифениламин в среда на кетони под налягане на газообразен водород и при повишена температура, в присъствие на редукционен катализатор, преставляващ смес от пресен и възстановен катализатор, характеризиращ се с това, че катализаторът отначало се подлага на въздействието на температура от 120 до 160' и на газообразен водород при налягане под 60 атм. В среда на съответен кетон, а след това се дозира р-нитроили р-нитрозодифенил-амин. Патентните претенции са формулирани в 1 точка.A method for the preparation of p-aminodiphenylamine derivatives from p-nitrodiphenylamine or from p-nitrosodiphenylamine in a ketone medium under hydrogen gas pressure and at elevated temperature, in the presence of a reduction catalyst, being a mixture of fresh and regenerated catalyst, characterized in that , that the catalyst is initially exposed to a temperature of 120 to 160' and to gaseous hydrogen at a pressure below 60 atm. In the medium of the corresponding ketone, and then p-nitro or p-nitrosodiphenyl-amine is dosed. The patent claims are formulated in 1 point.
