Procedure

The procedure shown for DMDS above was repeated except that a 1:1 weight blend of DMDS and DMPS was used as the presulfiding agent and 55 g of the 1:1 blend was dissolved in 3905 g of diesel oil to give a solution containing 1.0 wt % sulfur contributed by the blend. The results are given in Table 1 below.
