Abstract

A process for the preparation of 2- mercaptobenzthiazole which comprises reacting nitrobenzene or nitrosobenzene, hydrogen sulphide and carbon disulphide, the molar ratio of nitrobenzene or nitrosobenzene: hydrogen sulphide being from 1:3 to 1:6 or from 1:1.5 to 1:4, the molar ratio of nitrobenzene or nitrosobenzene: carbon disulphide being from 1:1 to 1:3 and the final reaction temperature being from 200 to 300 DEG C, is disclosed. Embodiments are disclosed wherein (a) nitrobenzene and H25 are reacted in a specified molar ratio under elevated temperature and pressure and the resulting reaction mixture is reacted with CS2 in a specified molar ratio at 200 to 300 DEG C; (b) nitrosobenzene, H25 and C52 are reacted in a specified molar ratio at 200 to 300 DEG C; and (c) nitrosobenzene and H25 are reacted in a specified molar ratio at 20 to 100 DEG C and the resulting reaction mixture is reacted with C52 in a specified molar ratio at 200 to 300 DEG C.
