Definitions
- Mineral oils of lubricating viscosity as for instance 45200 sec. Saybolt Univ. at 210 F. are in accordance with the present invention treated by incorporation of an agent of urea type from the group consisting of urea, substituted ureas, diaryl semicarbazides and diaryl carbazides. Instances of these are urea, dimethyl urea, tetramethyl urea, diphenyl urea, diphenyl semicarbazide, diphenyl carbazide, etc, compounds, diphenyl semicarbazide, diphenyl carbazide, diphenyl urea, dimethyl urea and urea are preferred.
- the amount employed is small, ranging from 0.001 to per cent, and ordinarily amounts of less than 1 per cent.
- Diphenyl carbazide is similarly incorporated with a lubricating oil.
- a mineral oil of lubricating viscosity containing a small amount of an agent from the group consisting of diphenyl carbazide and diphenyl semicarbazide.
Description
Patented Oct. 30, 1939 STATES PATENT OFFICE BENEFICIATION OF LUBRICATING OILS John M. Musselman and Herman P. Lankelma, Cleveland, Ohio, assignors to The Standard Oil 'Company, Cleveland, Ohio, a corporation of Ohio No Drawing. Application April 29, 1936, Serial No. 77,016
3 Claims.
! of the oil; A treatment therefore which can obviate such difllculty, and be simply and easily applied, is of fundamental importance and highly desirable.
To the accomplishment of the foregoing and 9 related ends, the invention, 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.
Mineral oils of lubricating viscosity, as for instance 45200 sec. Saybolt Univ. at 210 F. are in accordance with the present invention treated by incorporation of an agent of urea type from the group consisting of urea, substituted ureas, diaryl semicarbazides and diaryl carbazides. Instances of these are urea, dimethyl urea, tetramethyl urea, diphenyl urea, diphenyl semicarbazide, diphenyl carbazide, etc, compounds, diphenyl semicarbazide, diphenyl carbazide, diphenyl urea, dimethyl urea and urea are preferred. The amount employed is small, ranging from 0.001 to per cent, and ordinarily amounts of less than 1 per cent.
01 the various As an example: 0.01 per cent of urea is incorporated in a lubricating oil of 50 sec. at 210 F., S. U. and thoroughly mixed.
As another example: 0.01 per cent of diphenyl urea is incorporated with a lubricating oil similarly.
As another example: 0.01 per cent of diphenyl semicarbazide is incorporated in the lubricating 'oil similarly.
As another example: Diphenyl carbazide is similarly incorporated with a lubricating oil.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the the equivalent of such, be employed.
We therefore particularly point out and distinctly claim as our invention:
1. A mineral oil of lubricating viscosity containing a small amount of an agent from the group consisting of diphenyl carbazide and diphenyl semicarbazide.
2. A mineral oil of lubricating viscosity containing a small amount of diphenyl semicarbazide. 1
3. A mineral oil of lubricatingviscosity containing a small amount of diphenyl carbazide.
