  • Alkyl phosphate amine salts for use in lubricants
    Patent number: 11384308
    Abstract: A lubricant composition comprising an oil of lubricating viscosity and 0.01 to 5 percent by weight of a substantially sulfur-free alkyl phosphate amine salt, where at least 30 mole percent of the phosphorus atoms are in an alkyl pyrophosphate salt structure, exhibits good antiwear performance. In the phosphate amine salt, at least 80 mole percent of the alkyl groups are typically secondary alkyl groups of 3 to 12 carbon atoms.
    Type: Grant

  • PHOSPHOROUS CONTAINING ANTIWEAR ADDITIVES
    Publication number: 20200239501
    Abstract: A process is provided for preparing a salt of a hydroxy-substituted di-ester of phosphoric acid, comprising: (a) reacting a phosphating agent with a monohydric alcohol and with a propylene glycol, wherein the mole ratio of monohydric alcohol : propylene glycol is greater than about 4:1 and wherein an excess of the phosphating agent is employed such that the product mixture formed thereby contains phosphorus acid functionality; and (b) reacting the product mixture of step (a) with an amine. The product is useful as an antiwear agent.
