Description
Patented May 31, 1932 UNITED STATES PATENT OFFICE RUDOLPH R. ROSENBAUH, OF CHICAGO, ILLINOIS flied July 14, 1927.
My invention relates to lubricants, particularly to an improved lubricant product or base to be used in the compounding of lubrieating oils such as motor oils.
My improved base comprises primaril petroleum oil and a-metallic soap to whic are added an element for preventing jelling or stringing, and miscible vegetable castor oil. When such base is added to petroleum lubricating oils the resulting compound is a very eflicient lubricant particularly for internal combustion engines and is especially useful for preventing the formation of hard lazed surfaces as, for example, on friction ands such as are used in planetary transmissions.
In such lubricatin compounds a high percentage of the meta ic soap is very desirable; I preferably use a water insoluble metallic soap such as aluminum oleate, zinc oleate, aluminum stearate, or zlnc stearate. I-
have found that, ordinarily, with a petroleum natural oil of say about 200" to 300 (Saybolt) viscosity at 100 F., the maximum amount of soap whichcan be added without causing jelling or stringing is less than 5%. If more is dissolved in-the oil the whole mass will turn into a jell-like substance when cooled to atmospheric temperature. An important object of my invention is, therefore, to make it possible to use as high as 20%, or more, of the soap, andI accomplish this by adding a lead soap, such as lead oleateor lead naphthenate. I have found that even a very-small proportion, one-half of one per cent, or less, of the lead soap will not only prevent the jell formation but will make the resulting compound of absolutely stable viscosity on standing. If miscible castor oil is added the lubricating qualities and the nonchatter properties will be greatly increased and strengthened.
To produce my improved base the'petroleum oil is heated and the water insoluble metallic soap is gradually added to the oil during heating to become thoroughly dissolved therein, and then during heating of this mixture the lead soap is added. Castor oil may also be added but such oil must be thoroughly and permanently miscible with petroleum lubricating oils. Ordinarily com- Serial No. 286,492. Divided and this application Serial No. 205,848.
mercialcastor oil is not so miscible but in my co-pending application Serial Number 286,492, filed June 18, 1928, now Patent No. dated Aug. 19, 1930, as a division outof this application, I disclose a process for producing miscible castor oil and it is 1inch castor oil that I use in my improved ase.
For example, a proportion which I have employed and found very eificient, is as follows petroleum neutral oil of 200" to 300 viscosity (Saybolt) at 100 Fahrenheit.
20% metallic soap such as aluminum oleate.
1% lead soap such as lead oleate or lead naphthenate.
24%miscible castor oil.
The petroleum oil is 400 to 500 F. and during such heating the aluminum oleate is gradually added up to the full amount to become thoroughly and uniformly dissolved in the oil. If such mixture with the 20% soap content were allowed to cool it would become a thick jell. However,-
if during the heating process, the lead soap is added to the mixture and thoroughly dissolved therein, the resulting product will not jell or become stringy upon cooling. vNot only will the small quantity of lead soap pre vent the aluminum .oleate from causing ]elling, but the resulting compound will be of absolutely stableviscosity on standing.
Such compound of petroleum oil with the 20% of water insoluble soap made possible by the addition of only 1% lead soap, will be an efiicient base to be added to petroleum lubricatingoils to produce a highly eflicient motor oil and non-chatter lubricant. By the addition of the miscible castor oil a compound will result whose lubricating and nonchatter properties are greatly increased and strengthened. In compounding the base with lubricating oil the proportion of the base ranges from 5 to 20%.
As another example, the following proportions have been used; l
3500 lbs. petroleum oil--200". to 300" vis-. cosity (Saybolt) at 100 Fahr.
850 lbs. aluminum oleate.
80 to 100 lbs. lead oleate.
heated up to from to 200 lbs. miscible castor oil-depending on the strength desired.
400450 F.heating temperature.
Having described my invention, I claim as follows 1. A lubricating compound comprising a mineral oil, miscible castor oil, and water insoluble metallic soap.
2. A lubricant base comprising petroleum oil, aluminum oleate, and lead soap.
3. A lubricant base comprising petroleum oil, aluminum oleate, lead oleate and miscible castor oil.
4. A lubricant base comprising about 55% petroleum oil, about 20% aluminum oleate, about 1% lead oleate, and about 24% miscible castor oil. 1
5. A lubricating compound comprising a mineral oil, miscible castor oil, and water 1nsoluble metallic soaps one of which islead soap.
6. A lubricant compound comprising petroleum oil, aluminum soap, and lead soap.
7. A lubricant compound comprising pctroleum oil, aluminum oleate, lead soap, and miscible castor oil.
8. A lubricant compound comprising about lubricating oil, about 20% water insoluble metallic soa other than lead soap, and
I about 1% of lea soap for preventing jelling.
9. A lubricating compound comprising a petroleum oil, water insoluble metallic soap of the group consisting of aluminum and zinc soaps, and a lead soap. 7
10. A lubricant compound comprising petroleum oil, lead oleate and water insoluble metallic soap of the group consisting of aluminum and zinc soaps.
11. A lubricant compound comprising mineral oil, lead naphthenate, and water insoluble metallic soap of the group consisting of aluminum and zinc so ps.
In witness whereof, I hereunto subscribe my name this 8th da of July, 1927.
