Zusammenfassung:This solution is dealing with the procedure closed to the pressure filtration of the suspension related to the reaction mixture created, when producing N-cyclohexylbenzothiazolyl-2- -sulfenamide which is created based on the reaction between 2-merkaptobenzothiazole, as the melted raw product, high pressure reaction of aniline, carbon disulfide and sulphur with cyclohexylamine and sodium hypochlorite. The liquid system, separated of N-cyclohexylbenzothiazolyl-2-sulfenamide, consists of an organic and water phase, at the temperature of 11 up to 30 Celsius degree and at the absolute pressure of air or nitrogen, in the value of 260 up to 500 kPa and it is maintained in the emulated form in the area over the filtration barrier.
