Participants

Reaction Steps

5′-(Dibutyldithiocarbamyl)-2,5-dimercapto-1,3,4-thiadiazole (i.e., formula (I) where X is hydrogen and R1 and R2 are n-butyl radicals) was prepared in the following manner. In 100 grams of isopropyl alcohol 26 grams of dibutyl amine was combined with 16 grams of CS2 and held at a temperature of about 40° C. for about 1 hour to yield a dibutyl dithiocarbamic acid intermediate. Subsequently, 30 grams of 2,5-dimercapto-1,3,4-thiadiazole was added to the mixture along with 20 grams of 35 wt. % hydrogen peroxide. The mixture was reacted for about 1 hour at a temperature of about 28° C. to yield the liquid end product 5′-(dibutyldithiocarbamyl)-2,5-dimercapto-1,3,4-thiadiazole.
