Overbased MgO dispersions with high magnesium content and acceptably low viscosities are reproducibly prepared without gel formation by heating to 280-360&#xb0; C. a mixture of MgO, selected dispersants, low MW carboxylic acids, water and a combination of high boiling hydrocarbon and organic diluent, wherein water is more than 8%, typically more than 10% of the reaction mixture. No additional solubilizing or dispersing agents, promoters or reactants such as carbon dioxide, amines, alcohols etc are needed to obtain the desired dispersions. Compositions such as lubricating oils and fuels containing the overbased magnesium dispersions as additives are also disclosed.

Fuel compositions

An emulsifier blend includes at least one alkali metal sulfonate and at least one alkali metal alkyl salicylate. The emulsifier blend can be combined with a lubricant oil to provide a water-miscible lubricating oil concentrate capable of forming a stable aqueous emulsion when added to an aqueous medium.

Emulsifier blends for lubricating oils

A process and composition for forming a non-Newtonian oil composition in the form of a grease comprising an overbased calcium salicylate and solid particles of colloidally dispersed calcium carbonate in the form of calcite is disclosed wherein the process comprises the steps of heating overbased calcium salicylate, amorphous calcium carbonate, and a converting agent comprising a fatty acid of twelve to twenty-four carbon atoms in an oleaginous medium, and then adding sufficient water, alcohol, and carbon dioxide to the mixture to complete the conversion of the amorphous calcium carbonate to calcite.

Overbased calcium salicylate greases

A salicylate is disclosed, which has detergent and anti-oxidant properties, for use as a metal based detergent additive. An alkyl salicylic acid is derived from the alkylation of salicylic acid with styrene. The neutralization and subsequent overbasing of neutral salt results in an alkaline detergent, such as calcium or magnesium salicylate. The resulting detergent is a salicylic acid having multi-styrenated chains, which provide oil solubility. A method for making such a detergent is also disclosed.

Metal-containing neutral and overbased salicylates based on styrenated salicylic acid

The invention is a process for producing alkaline earth metal salicylates for use as lubricant detergents and to compositions prepared by the process. The process comprises two steps. Step 1 is the alkylation of salicylic acid is conducted using Cor greater linear &#x3b1;-olefins to produce alkyl salicylic acids in commercially acceptable yields. The alkylation conditions produce predominately mono-substituted para alkyl salicylic acids that are oil soluble. Step 2 is the oil soluble acid is subsequently neutralized and overbased by carbonation of lime using COin the presence of a promoter and a surfactant. The reaction mixture after overbasing is filtered and solvents are removed by distillation. Alternatively, alkyl salicylic acid can be reacted with a previously overbased alkaline earth sulfonate, e.g., calcium sulfonate, to produce alkaline earth salicylate salts comprising varying percentages of dispersed alkaline earth carbonate salts. In this method, no filtration of the end product is required, and, thus, it is commercially preferred.

Method for producing lubricant detergents

An overbased calcium sulfonate detergent having a high viscosity is characterized by forming a clear solution in lubricating oil, having a TBN of about 400 or more, and having a viscosity of at least 180 mm /s at 100&deg; C. The high viscosity of the detergent allows for reduction in expensive high viscosity oil components of marine cylinder oils while maintaining selected TBN and viscosity parameters in the finished oil.
