Product 1

HCID 8896Magnesium Acetate

Procedure

To a 4-liter beaker are charged 1890 g kerosene, 94 g (about 0.3 equiv.) dodecylbenzenesulfonic acid and 64 g (about 1.067 mole) glacial acetic acid. The contents are stirred until homogeneous. With stirrer on, 1250 g (about 21.44 moles) magnesium hydroxide is added followed by 218 g kerosene and 154 g sorbitan mono-oleate. A magnesium sulfonate and magnesium acetate are formed in situ. The mass is stirred for three hours. The viscosity of the mass is about 5000 cps. The magnesium content is calculated at about 14.2% for 3670 g total suspension. There was no separation of layers after 4 months of standing.
