Application filed October 4, 1921. Serial No. 505,318.
This invention relates to the formation of. additional normal lead oleate, waterand normal lead oleate and the preparation of lubricating compounds therefrom. I have found that in the production of 5 lubricants containing lead soaps it is desirable to avoid the use of the basic lead salt and employ the normal salt. The basiclead salt, 2Pb(C ,H COO) .PbO, is sticky and stringy in character, it is not permanently such as elain or red oil, and carbon dioxid under conditions to form the normal lead salt and then mix the lead soap with a suitable cylinder oil or other lubricating oil to form a homogeneous lubricating compound.
According to my present knowledge and belief, the chemical reactions of the process proceed-substantially as follows In the preferred manner of carrying on the process the lead oxid and ole'ic acid are introduced into a mixing kettle and carbon dioxid 40- is blown thru the'mixture while heated sufliciently for the reaction. used varies from about 350]? to 500 F. If desired mechanical agitating means may be employed, especially during the first stages of the reaction. It is probable that the lead oxid and oleic acid react immediately to form the basic salt. The carbon dioxid then attacks the basic sale with the formation of the normal salt and some lead carbonate, and the 5 oleic acid reacts with the carbonate yielding The temperature carbon dioxid. The agitation and heating may be continued until there is no free acid present and the lead oleate is thenallowed to cool somewhat, for example, to about 200 F., when lubricating oilis added and mixed with the soap to form the desired com-; pound. I In lead soap lubricating compounds, such as car "oils, for instance, made by prior methods of manufacture, a greater or less quantity of insoluble material is contained in the compounds which readily settles out. The settlings may be attributed to the use of the basic lead oleate and to the presence of lead st'earate and palmitate which are frequently found in car oils. These settlings are not only insoluble in oil but moreover have no lubricating value. When preparing lubricating compounds in accordance with the present invention involving theme of the normal lead oleate a homogeneous compound is formed with the leadsoap completely in solution in the mixture and withtno deposits or settlings. The presence of the normal lead oleate adds to the lubricating value of the compound, since the normal salt has an unctuous'quality and is, in fact, itself suitable for use as a lubricant.
The normal soap also possesses the property of reducing the viscosity at low temperatures of the compound into which it enters below that of the oil stock with which it is mixed. The effect of the normal soa on parafiin oils is especially-marked, the o eate 5 apparently hindering in some .manner the formation of wax crystals. Ifhe elfect on asphalt base oils is in a less degree but the viscosity of the compound is also reduced at low temperatures below that of the oil stock. The practice of my invention is thus particularly adapted for the production of lubricants adapted for use at cold temperatures.
Various lubricating com ounds may be 95 prepared'in accordance wit my invention, such for example as car oils, driving 'ournal compounds and other lubricants. e proportion of oleate used varies with the type of product desired. For example, summer 100 car 'oils require less oleate than winter car oils. The proportion may vary from as low as 2%10 which is the proportion ordinarily used for car oils, for instance, to the 5 higher proportions used in the preparation of eases.
bviously many modifications and variations of the invention, as hereinbefore set forth-,may be made without departing from mthe spirit and scope thereof and therefore, only such limitations should be imposed as are indicated in the appended claims.
What I claim is 1. The rocess of manufacturing lubri- 15 cants whic comprises heating a mixture of.
vlead oxid and oleic acid, passing carbon dioxid through the heated ingredients to cause the formation of normal lead 'oleate and then mixing said oleate with lubricating oil.

'4. A liquid lubricant comprising a mineral 30 lubricating oil compounded with a lead oleate vcompletely and permanently soluble in the oil, and having a viscosity at low temperatures lower than the uncompounded oil. In witness whereof I have hereunto set my 36 hand this 26th day of Sept, 1921.
