To a three neck flask were added 102.1 grams of the dithiophosphoric acid obtained from Example 9 and 10.6 grams of calcium hydroxide. The reaction was heated to 42° C. The temperature then increased rapidly to 115° C. The reaction was placed in a water bath and the temperature decreased back to 30° C. This gave a viscous product, to which 20.3 grams of triethylene glycol monobutyl ether were added. The reaction was then heated back to 98° C., and was then stopped heating. After cooling back to 37° C., 4.4 grams of 35% hydrogen peroxide were added over a period of one and one half hours. The reaction was then heated back to 119° C. under vacuum and water was removed by distillation. The product was then filtered with diatomaceous earth.
