  • Overbased calcium salicylate greases
    Patent number: 7407920
    Abstract: 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.
    Type: Grant

  • Metal-containing neutral and overbased salicylates based on styrenated salicylic acid
    Patent number: 7087557
    Abstract: 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.

  • Sulfonate grease improvement
    Patent number: 5338467
    Abstract: The process of forming a non-Newtonian oil composition in the form of a grease comprising an overbased calcium sulfonate and solid particles of colloidally dispersed calcium carbonate in the form of calcite which comprises heating overbased calcium sulfonate, amorphous calcium carbonate and a converting agent comprising a fatty acid of twelve to twenty-four carbon atoms in an oleaginous medium.

  • Sulfonate greases
    Patent number: 5308514
    Abstract: High performance overbased calcium sulfonate greases comprising up to about 28% by weight overbased calcium sulfonate, solid particles of colloidally dispersed calcium carbonate essentially in the form of calcite, a calcium soap of a fatty acid of twelve to twenty-four carbon atoms, and oleaginous vehicle wherein at a concentration of about 28% by weight overbased calcium sulfonate said greases have a worked cone penetration rating of less than about 295.
