Reaction Steps

3,5-di-t-butyl-4-hydroxybenzyl bromide was reacted with the ammonium salt of dicyclohexylphosphinodithioic acid to obtain 3,5-di-t-butyl-4-hydroxybenzyl dicyclohexylphosphinodithioate, m.p. 129°-131° C, which on testing lasted 475 hours* longer than the control. The total number of hours required to reach failure was 1.9 times that of the control.
