Procedure

To the reactor of Example 1 were charged 150 g high-boiling hydrocarbon oil, 28.2 g naphthenic acids, and 3.0 g commercial technical grade magnesium hydroxide. The contents were agitated and heated to 200° C. The contents were cooled and 20.3 g (0.35 mole) commercial technical grade magnesium hydroxide was added. The contents were heated to 135° C. Acetic acid (42.0 g, 0.7 mole) was added dropwise while maintaining the temperature at 125°-135° C. to form magnesium acetate in situ. After all of the acetic acid was in, the contents were heated above 280° C. to remove water and decomposition products from the magnesium acetate formed in situ. The resulting product was bright and weighed 185.8 g. Upon centrifugation of 90-gram sample, the sediment was 0.1 g. The magnesium content of the bright supernatant liquid was calculated at about 5.2%; the conversion of commercial technical grade magnesium hydroxide to the fluid dispersed form of MgO was calculated at 98.5%.
