Procedure

A solution of hexamethylene bis (thiosulphate) sodium salt (100 g. 0.282 mol) in 500 ml of water at 70° C. was added slowly to a stirred solution of 133 g (0.568 mol) of diphenylguanidine hydrochloride in 700 ml water. The mixture was cooled and the solid which separated was collected. Recrystallisation from a mixture of equal parts by volume of methanol and toluene gave 154 g (77.1%) of hexamethylene bis (thiosulphate) bis (diphenylguanidinium) salt, m.p. 151°-153° C.
