Description
Patented Dec. 12, 1939 ATENT oFFicE LUBRICATING OIL Joseph Cole, Whiting, End, assignor to Sinclair Refining Company, New York, N. Y., a corporation of Maine No Drawing; Application September 23, 1936, Serial No. 102,167
41 Claims.
My invention relates to improvements in pour depressors, compounding agents to be added to petroleum lubricating oils to lower the temperature at which such oils cease to flow, and in methods of making such pour depressors.
I produce the pour depressor of this invention by mixing stearic acid with chlorinated parafiin Wax and treating this mixture with anhydrous aluminum chloride.
Specifically, the pour depressor of this invention is conveniently produced as follows: A mixture of 200 parts (by weight) of chlorinated parafiin wax containing about 43% (by weight) of chlorine and 100 parts of stearic acid is heated to 120 F. and maintained at that temperature for 30 minutes. 15 parts of anhydrous aluminum chloride is added to the resulting mixture, and
the temperature of this mixture is gradually increased, while maintaining thorough stirring,
until a temperature of 580 F. is attained. The mixture may then be filtered while still hot. The product of this'aluminum chloride treatment is the pour depressor of my invention. It remains liquid at room temperature.
This pour depressor may be compounded with petroleum lubricating oils in proportions rang ing from a fraction of a percent up to several percent, from 0.1% to 1% or somewhat more for example. Added to one Pennsylvania lubrieating oil originally having a pour test of 25 F.,
0.5% (on the oil) of this pour depressor produced a compounded product having a pour test pour depressor than the method by which of 15 F. Such reductions in the pour test are attained without impairment of the viscosity index of the oil, but the compounded products are usually darker in color than the oil before additior of the pour depressor.
My invention includes this pour depressor and petroleum lubricating oils compounded with this pour depressor as well as the method of making the pour depressor. However, I do not now have any better mode of identification of the 10 it is made.
I claim:
1. A method of making a pour depressor comprising reacting chlorinated paraflin wax with 1g; stearic acid in the presence of anhydrous aluminum chloride, and removing the solid constituents from the liquid product of this reaction.
2. A pour depressor which comprises the product produced as in claim 1. 20
3. compounded petroleum lubricating oils comprising the pour depressor produced as in claim 1.
4. The method of depressing the pour point of a petroleum lubricating oil which comprises reacting chlorinated paraflin wax with stearic acid 25 in the presence of anhydrous aluminum chloride, to form a liquid product, removing solid constituents from this liquid product, and adding the liquid product to the petroleum lubricating JOSEPH COLE.
