Description

Patented July 16, 1*
UNITE SATES PATENT LUBBICATING OIL PREPARATION Herman P. Lankelma, Cleveland, Ohio, asslgnor to The Standard Oil Company, Cleveland, Ohio, a corporation of Ohio 8 Claims. (01. 252-51) This invention relates to lubricating oils, and more particularly the beneficiation of mineral lubricating oils which are subject to high temperature usage; and it is among the objects of the invention to provide an oil which is especially durable in high temperature usage, as in internal combustion engines, etc.
To the accomplishment of the foregoing and related ends, the invention, then comprises the 10 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.
A mineral lubricating oil stock of desired viscosity is treated by incorporation of a small amount of a hydro-compound from the group consisting of hydroquinine, hydroquinidine and hydrocinchonine. These compounds readily dissolve and disseminate, and the amounts employed may in general be from 0.001 to 5 per cent, and "oil stocks of for instance 45-200 sec.
at 210 F. Saybolt Universal may be treated.
As an example: 0.01 per cent of hydroquinine is incorporated in an oil of 50 sec. at 210 F. Saybolt Universal, being thoroughly mixed.
Similarly with the other hydro-compounds.
This application is a division of my application Ser. No. 99,450, filed Sept. 4, 1936.
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 ofthe following claims, or
the equivalent of such, be employed.
ll therefore particularly point out and distinctly claim as my invention:
1. A process of preparing lubricating oils,
which comprises beneficiating a mineral oil capable of lubricating viscosity at high temperature by incorporating therewith a small amount of a hydro-compound of the group consisting of hydroquinine, hydroquinidine, and hydrocinchonine.
2. A process of preparing lubricating oils, which comprises beneficiating a mineral oil capable of lubricating viscosity at high temperature by incorporating therewith a small amount of hydroquinine.
3. A process of preparing lubricating oils, which comprises beneficiating a mineral oil capable of lubricating viscosity at high temperature by incoporating therewith a small amount of hydroquinidine.
4. A process of preparing lubricating oils, which comprises beneficiating a mineral oil capable of lubricating viscosity at high temperature by incorporating therewith a small amount of hydrocinchonine.
5. A lubricating composition comprising a mineral oil capable of lubricating viscosity at high temperature and a small amount of a cinchonine.
