Definitions

  • This invention is based upon the discovery that addition to the oil of small amounts of triphenylphosphite (CcHsO)3P accomplishes the above objects. It is found that when corrosion of the type outlined above occurs, especially if the oil be one which has been produced by a process of solvent refining, in which type the corrosive properties appear to be the most marked, that the oil can be rendered substantially non-corrosive under conditions more strenuous than normal automotive use by the addition of controlled amounts of this compound, viz, triphenylphosphite.
  • CcHsO triphenylphosphite
  • Triphenylphosphite is an organic compound having the following graphic formula:
  • This compound may be prepared by the reaction of phenol and phosphorus trichloride, in the proportions of three molecular amounts of phenol to one of phosphorus trichloride.
  • the reaction mixture is heated until the evolution of hydrogen chloride ceases.
  • This evolution of HCl gas may be measured, since it furnishes a convenient means of estimating and controlling the progress of the reaction.
  • the resulting product, triphenylphosphite may be purified, if desired, by a process of fractional distillation, the pure compound boiling at 209-210 C. at 1 mm. mercury pressure.
  • it may be used either as produced or in the fractionated form, although the use of the fractionated compound is preferred.
  • each test is the equivalent of exposure of the oil to use in an automobile for 1200 miles of continuous 60 mile an hour driving, a condition far more rigorous than anyencountered in normal use.
  • the hearings in the engine were new for each test, and were carefully weighed before and after to determine loss in weight.
  • the used oil was measured, and is recorded as being indicative of the corrosive nature of the oil.
  • the inhibitor used was the fractionated triphenylphosphite of 2052i5 C. boiling point at 1 mm. mercury pressure described above.
  • An indicative test of considerable merit may be made in the laboratory by suspending a portion of a cadmium-silver alloy bearing in a bath of the oil under test in a glass container, maintaining the oil at about 350 F., and passing air through the oil in contact with the bearing metal.
  • Convenient conditions are: 30 gm. oil,2,000ml-. air per hour, 22
  • novel corrosion inhibting' ingredient herein disclosed namely triphenylphosphite
  • triphenylphosphite is an eflective agent for the prevention of corrosion of automotive parts, particularly the newer type alloy bearings, when introduced in proper amounts into an oil otherwise highly corrosive.
  • triphenylphosphite is a water clear oil, freely miscible with hydrocarbons, and may be added in any proportion without darkening or deepening the color of the oil. When so added, it has no tendency to separate from the oil under conditions of storage or use.
  • a method of lubricating bearing surfaces in internal combustion engines when subjected to conditions of operation which comprises maintaining between bearing surfaces, one of which is an alloy formed chiefly of a metal selected from the class consisting of cadmium and copper, a film of lubricating oil which initially produces an effective lubricating action but which would normally tend to corrode the aforesaid alloy, and maintaining the efiectiveness of the lubricating oil by incorporating therein triphenylphosphite in a small but suflicient proportion substantially to retard the corrosion.
  • a method of lubricating bearing surfaces in internal combustion engines when subjected to conditions of operation which comprises maintaining between bearing surfaces, one of which is analloy formed chiefly of a metal selected from the class consisting of cadmium and copper, a film of lubricating oil which initially produces an effective lubricating action but which would normally tend to corrode the aforesaid alloy.
