Reaction Steps

To a three neck flask was added 204.3 g of the dithiophosphoric acid mixture from Example 3, lot RJT-543-244, and 27.1 g of zinc oxide. The mixture was heated to 65° C. and mixed at this temperature for four hours. The temperature was then increased to 100° C. The temperature was then gradually increased to 110° C. under vacuum while distilling off any water produced from the reaction. After mixing at 110° C. for 1 hour while under vacuum, the final product was filtered with diatomaceous earth.
