실험 절차

Chlorine gas (17.5 g/0.25 mole) was passed at 0 to 50C into a suspension of 2,2'-dithiobisbenzthiazole (83 g/0.25 mole) in chlorobenzene (600 ml). Mercaptoethanol (39 g/0.5 mole) was then added drop-wise to this solution, followed by stirring for 7 hours at room temperature. The precipitated product was filtered off, mixed with methylene chloride (500 ml) and washed with 5% NaHCO3 solution (500 ml). The organic phase was concentrated by evaporation. A yellowish-brown oil (102 g) was obtained, which crystallised after a short time. m.pt.: 65 to 68° C.
