Procedure

2,6-Dimethyl-3-hydroxy-4-t-butylbenzyl bromide was reacted with the ammonium salt of dicyclohexylphosphinodithioic acid to obtain 2,6-dimethyl-3-hydroxy-4-t-butylbenzyl dicyclohexylphosphinodithioate, m.p. 113°-116° C, which on testing lasted 150 hours longer than the control. The total number of hours required to reach failure was 1.3 times that of the control.
