- the monoalkenyl succinimides of tetraethylene pentamine have the formula wherein R is a hydrocarbon radical having a molecular weight from about 400 to about 3000; that is, R is a hydrocarbon radical containing about 30 to about 200 carbon atoms.

- the alkenyl radical is obtained by polymerizing an olefin containing from 2 to 5 carbon atoms to form a hydrocarbon having a molecular weight ranging from about 400 to about 3000, more preferably, 900 to 1200.
- Such olefins are exemplified by ethylene, propylene, l-butene, 2-butene, isobutene, and mixtures thereof.

- This reaction can proceed in a mole ratio of the polyolefin to the maleic anhydride of 1:1 to 1:10, preferably from 1:1 to 1:5.
- the reaction temperature can vary from 300 F. to 450 F. Because of the greater yield of products obtained thereby, it is preferred to use the high range of temperatures (e.g., 375 F. to 450 F.).

Description
United States Patent 3,210,283 LUBRICANT CONTAINING ALKENYL SUCCIN- IMIDE AND HYDROXYPOLYAMINE Frank A. Stuart, Orinda, and Robert G. Anderson, Novato, Calif., assignors to California Research Corporation, San Francisco, Calif, a corporation of Delaware No Drawing. Filed June 18, 1963, Ser. No. 288,628 4 Claims. (Cl. 252-515) This application is a continuation-in-part of Frank A. Stuart and Robert G. Anderson, US. application Serial No. 102,366, filed April 12, 1961, now abandoned.
This invention pertains to lubricating oil compositions having incorporated therein the metal-free detergents, alkenyl succinimides, in combination with certain hydroxypolyamines.
Alkenyl succinic anhydrides and numerous derivatives thereof are well known in the art. For example, alkenyl succinic anhydrides in which the alkenyl radical contains from 5 to 20 carbon atoms are taught as corrosion inhibitors in lubricating oil composition. Also products obtained by reacting such alkenyl succinic acid anhydrides with monoamines are taught as ferrous corrosion inhibitors for lubricating oil compositions.
However, the above known alkenyl succinimides are not useful as detergents in lubricating oil compositions. In contrast thereto, the alkenyl succinimides which are described herein are new compounds which are useful as detergents in lubricating oil compositions.
Present day internal combustion engines operate at high speeds and high compression ratios. When used in the so called city stopand-go driving, which includes the greater part of the driving condition for a large percentage of todays automobiles, the internal combustion engines do not reach the most efiicient operating temperatures. Under city driving conditions, large amounts of partial oxidation products are formed, and reach the crankcase of the engine by blowing past the piston rings. Most of these partial oxidation products are oil insoluble, tending to form deposits on the various operating parts of the engine, such as the pistons, piston rings, etc. For the purpose of preventing the deposition of these products on the various engine parts, it is necessary to incorporate detergents in the lubricating oil compositions, thus keeping these polymeric products highly dispersed in a condition unfavorable for deposition on metals.
For the most part, the various detergents which are added to crankcase oils to reduce this formation of sludges and varnishes are metal organic compounds, particularly those compounds wherein the metal is linked to an organic group through an oxygen atom. Although these metal-containing organic compounds have some effectiveness as detergents for dispersing the precursors of deposits within the oil itself rather than permitting them to form added deposits on the engine parts, they have the disadvantage of forming ash deposits in the engine. These ash deposits lower engine performance by fouling spark plugs and valves, and contributing to preignition.
Lubricating oil compositions containing N-substituted polyamine alkenyl succinimides as metal-free detergents are described in Frank A. Stuart, Robert G. Anderson and Alan Y. Drummond copending application Serial No. 835,437, filed August 24, 1959. The addition thereto of certain polyamines markedly improves the effectiveness of such detergents as lubricating oil additives.
It is a particular object of this invention to provide lubricating oil compositions which are compounded with a metal-free detergent in combination with certain hydroxypolyamines.
Therefore, in accordance with this invention, it has been discovered that lubricating oil compositions par- 'ice ticularly useful for heavy-duty service are obtained by incorporating certain hydroxyalkylalkylenepolyamines and N-substituted monoalkenyl succinimides derived from tetraethylene pentamine in oils of lubricating VIS- cosity.
By the use of lubricating oil compositions containing the N-substituted alkenyl succinimides in combination with the hydroxypolyamines as described herein, diesel and gasoline engine parts remain remarkably free of deposits and varnish, even under severe operating conditions.
The monoalkenyl succinimides of tetraethylene pentamine have the formula wherein R is a hydrocarbon radical having a molecular weight from about 400 to about 3000; that is, R is a hydrocarbon radical containing about 30 to about 200 carbon atoms.
The R radical of the above formula, that is, the alkenyl radical, is derived from an olefin containing from 2 to 5 carbon atoms. Thus, the alkenyl radical is obtained by polymerizing an olefin containing from 2 to 5 carbon atoms to form a hydrocarbon having a molecular weight ranging from about 400 to about 3000, more preferably, 900 to 1200. Such olefins are exemplified by ethylene, propylene, l-butene, 2-butene, isobutene, and mixtures thereof. Since the methods of polymerizing the olefins to form polymers thereof is immaterial in the formation of the new compound described herein, any of the numerous processes available can be used therefor.
These alkenyl succinimides of tetraethylene pentamine can be prepared by reacting maleic anhydride with an olefinic hydrocarbon, followed by reacting the resulting alkenyl succinic anhydride with tetraethylene pentamine.
The reaction between a polyolefin and maleic anhydride is an uncatalyzed addition reaction which should not be confused with a copolymerization reaction such as that obtained with a vinyl monomer and maleic anhydride. This reaction can proceed in a mole ratio of the polyolefin to the maleic anhydride of 1:1 to 1:10, preferably from 1:1 to 1:5. The reaction temperature can vary from 300 F. to 450 F. Because of the greater yield of products obtained thereby, it is preferred to use the high range of temperatures (e.g., 375 F. to 450 F.).
In the reaction between an alkenyl succinic acid anhydride and tetraethylene pentamine, in which reaction the temperatures are from 220 F. to 500 F., preferably from 300 F. to 400 F., the yield of the imide is extremely high even though the reactants are used in equal molar ratios. This is surprising, since under the conditions of the reaction there is an excess of secondary amino groups, and any reaction with the secondary amino groups would lead to amide formation; thus preventing imide formation.
Since the reaction between the polyolefin and maleic anhydride may not go to completion, the resulting alkenyl succinic anhydride may contain some unreacted polyolefin. As it may not be desirable to separate out this unreacted polyolefin at this stage, the resulting imide formed by reaction of the alkenyl succinic anhydride and the diamine will contain this polyolefin as an impurity which can be a diluent in the formation of lubricating oil compositions. However, if it is so desired, this unreacted polyolefin can be removed by precipitation, for example, by acetone or methanol from a hydrocarbon solution.
The particular hydroxyalkylalkylenepolyamines which are effective herein in combination with alkenyl succinimides of tetraethylene pentamine are of the formula reaction mixture was cooled to 150 F. and 700 cc. of hexane added; after which the mixture was filtered under vacuum. After vacuum distillation to remove the hexane from the filtrate, the product was maintained at 350 F. at an absolute pressure of 10 mm. Hg for one hour to mole ratio is from 3:1 to 100:1, preferably from 10:1 to 65 The preparation of the alkenyl succinimidcs of tetraalkylene pentamine is illustrated in the following examples.

It is readily seen from the data set forth hereinabove in Table I that lubricating oil compositions containing the combination. of the above-defined hydroxypolyamines and alkenyl succinimides of tetraethylene pentamine as described herein are superior as lubricating oil compositions for the lubricating of internal combustion engines to the compositions containing only the alkenyl succinimides of tetraethylene pentamine. On the other hand, it is noted that monoamines, for example, dodecylamine, have a detrimental effect on the described succinimides as ashless detergents in lubricating oil compositions.
In addition to the compositions described hereinabove, lubricating oil compositions may also contain other detergents, viscosity index improving agents, rust inhibitors, oiliness agents, grease thickening agents, etc.
