Abstract
This invention relates to magnesium carboxylate and/or phenate-sulfonate complexes, processes for their preparation and uses therefor, particularly as fuel additives for vanadium-containing fuels.
Claims2
A process of preparing a stable dispersion of a basic, magnesium-containing, inorganic compound having a magnesium content of about 12.5% to about 14.6% which comprises (a) admixing (1) a glycol ether solution of an oil-soluble magnesium alkoxide-carbonate complex, said complex having been prepared from a glycol ether having not more than 8 carbon atoms, (2) an oil-soluble sulfonate, (3) a carboxylate- and/or phenate dispersing agent, (4) a volatile carrier and (5) water in excess of the stoichometric requirement for hydrolysis of said magnesium-alkoxide-carbonate complex,
- b. hydrolyzing the magnesium-alkoxide-carbonate complex to an oil-soluble magnesium-containing inorganic compound, at reflux temperature for a period of about 1 to 2 hours, and then
- c. removing the volatile carrier to the desired viscosity,
- d. said process being characterized further in that the magnesium-alkoxide-carbonate complex of step (a) is prepared by a process comprising
- 1. reacting magnesium with a glycol ether having not more than 8 carbon atoms to form the magnesium alkoxide;
- and
- 2. reacting the magnesium alkoxide with from 0.5 to about 1.5 mols of carbon dioxide per mole of said magnesium alkoxide to form a magnesium-alkoxide-carbonate complex.
