Procedure

A solution of zinc methanesulfonate was prepared from 7 parts zinc oxide, 22.6 parts of a 70% aqueous solution of methanesulfonic acid and 41.4 parts water. To this solution was added 15.5 parts tetraethylenepentamine over a one hour period. A solution of 375.5 parts Example 1 product in 176.7 parts Promar oil was added, and the materials were reacted at 150° C. for two hours under a vacuum of 2 mm of mercury. The product, after dilution with 160.7 parts Promar oil, and filtration, contained 0.40% nitrogen, 0.45% zinc and 0.36% sulfur.
