more effectively in guarding the oil against break-down, but also in maintaining its body and lubricating qualities in drastic usage, such as in internal combustion engines.
To the accomplishment of the foregoing and i elated ends, theinvention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description setting forth in detail certain. illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be employed.
Sulphur is reacted upon an aliphatic amine, by heating the materials together in suitable proportions. If molar proportions be taken, no excess of uncombined component is left in the reaction mass. The sulphur employed may be conveniently in finely divided form or flour of sul- 2 phur. In general, the aliphatic amines of suitable boiling point so reactable can be used, some being more practically desirable than others. In-
stances of such amines are triamylamine, dimethylamine, octylamine, stearylamine, butylamine, etc. Thus, molecular proportions of triamylamine and sulphur are heated together to approximately 200- F. for about thirty minutes. Analogously also, the sulphur products of the other amines may be prepared. The reaction product is then incorporated in a-lubricating oil base,such
-as a mineral oil of lubricating viscosity, as for is compounded with-0.1 per cent of the reaction product of sulphur and butylamine.
As another example: Lubricating oilsimilarly is compounded with 0.1.per cent of the reaction product of sulphur and octylamine.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent of such, be employed.
We therefore particularly point out and distinctly claim as our invention:
, 1. A process of preparing lubricating oils, which comprises heating molar proportions of triamyla small amount of the reaction product in a mineral oil of lubricating viscosity.
3. A process of preparing lubricating oils, which comprises heating molar proportions of butylamine and sulphur to reaction, and incorporating a small amount of the reaction product in a mineral oil of lubricating viscosity.
4. A process of preparing lubricating oils, which comprises heating molar proportions of an aliphatic amine and sulphur to reaction, and incorporating a small amount of the reaction product in a mineral oil of lubricating viscosity.
5 A lubricant comprising a mineral oil of lubricating viscosity and a small proportion of the reaction product of heating triamylamine and reaction product of heating butylamine and sulphur.
8. A lubricant comprising a mineral oil of lubricating viscosity and a small proportion of the reaction product of heating an aliphatic amine and sulphur.
