Stable oil dispersible magnesium hydroxide slurries

摘要

Stable, oil dispersible, aqueous dispersions of magnesium hydroxide useful as deposit control additives for residual fuels can be prepared. These slurries, of magnesium hydroxide contain generally: (A) 20-70% Mg(OH)2 having a particle size of 50 to 1.0 micron; (B) 79-29% water; (C) 1.0-8.0% of a water-in-oil emulsifying agent having an HLB value of from 2 to 11; (D) 0.1-6% of a water soluble water-in-oil emulsifying agent having an HLB value of from 10 to 40; Said dispersion having a Brookfield Viscosity of from 100-5000 cps.
