Versuchsvorschrift
In a process for purifying crude molten 2-mercaptobenzothiazole, prepared by reacting aniline carbon disulfide and sulfur at elevated temperature and pressure, in which the purification includes the steps of separating dissolved alkali metal salt of 2-mercaptobenzothiazole from undissolved impurities, treating the dissolved alkali metal salt of 2-mercaptobenzothiazole with an excess of a non-oxidizing mineral acid to precipitate a slurry of purified 2-mercaptobenzothiazole, separating the purified 2-mercaptobenzothiazole solids from the slurry to obtain 2-mercaptobenzothiazole solids, washing the solids with water, and drying the purified 2-mercaptobenzothiazole, the improvement comprising; forming said dissolved alkali metal salt at 2-mercaptobenzothiazole and said dissolved impurities by the steps of
