Abstract

Benzthiazole 2 - N:N - di - isopropysulphenamide is obtained in a substantially dry state from a mixture containing it by adding water, agitating the mixture and centrifuging at a temperature sufficiently high to keep the sulphenamide in a molten state, e.g. 60-100 DEG C. Examples show the process applied to the methanol solution obtained by reacting bisbenzthiazole disulphide, N-chloro-di-isopropylamine and di-isopropylamine with or without separation of the solid phase obtained on addition of the water. The method is also applicable to the crude solid sulphenamide.
