Cyclohexylbromide was reacted with the ammonium salt of dicyclohexylphosphinodithioic acid to obtain cyclohexyldicyclohexylphosphinodithioate, m.p. 82°-85° C, which on testing lasted 1250 hours* longer than the control. The average number of hours required to reach failure was 3.5 times that of the control.
