Procedure

A solution of 5.9 g (0.026 m) of dipotassium 3,5-dimercapto-1,2,4-thiadiazole in 50 ml of ethanol was added slowly with agitation to an ethanol solution of 7.89 g (0.026 m) of dibutyltindichloride. The resulting reaction mixture was refluxed for 2 hours. A light yellow solid was isolated following several washes with ethanol and drying at 100° C. for 5 hours. Elemental analysis and other data of the product are recorded in Table III. The extreme pressure and antiwear characteristics of two base greases containing 5% of the solid product are listed in Table IV.
