- Ashless lubricating oil detergents are provided by the reaction product of (A) a carboxylic acid or acid anhydride containing addition copolymer having at least two acid or anhydride groups, optionally composed in part of monomeric carboxylic acid or anhydride,
- the present invention is directed to novel materials useful, for instance, as additives for lubricating oils. More specifically the invention concerns the reaction products of a carboxylic acid copolymer, an aminophenol, and an amine, and the alkaline metal salts of the reaction products which materials find use as lubricating oil detergents and anti-oxidants. If desired the carboxylic acid component can be composed in part of monomeric carboxylic acid or anhydride.
- the base oil-soluble reaction product of a copolymeric carmboxylic acid, an aminophenol and an amine when added to a base oil of lubricating viscosity in small amounts, provides the oil with excellent dispersant and anti-oxidant properties.
- the reaction product can also be used as an alkaline metal salt and can include monomeric carboxylic acid, for instance, reacted as an anhydride.
- the sequence in which the reactants can be combined to afford the oil-soluble additives of the present invention may be varied depending upon the products which are being prepared. Regardless of the sequence of reaction and reaction conditions, however, about 0.1 to 2 moles, preferably about 0.2 to 1 mole, of total amine per average reactive carboxylic acid group (including an hydride groups as one such carboxyl group) is generally reacted per mole of reactive acid group, and at least about 0.2 mole, preferably up to about 2 moles, of the aminophenol per average basic nitrogen atom present in a mole of amine reactant, is reacted.

- the average molecular weights of the copolymeric carboxylic acids may often vary from about 200 to 40,000, preferably about 400 to 10,000.
- Particularly preferred acid reactants are the copolymer resins of the above-described vinyl compounds and maleic anhydride, for instance, styrene-maleic anhydride resins.
- a mole ratio of vinyl compound to maleic anhydride is of about 1 to 4:1, preferably 1 to 3:1 is employed to prepare the copolymer.
- These copolymer resins may contain repeating vinyl compound-maleic anhydride units and preferably have an average molecular weight of about 400 up to about 40,000 or more, preferably about 400 to 3,000.
- the melting points of the lower molecular 3 Weight copolymers will generally range from about 80 to 300 C. as determined by the Fisher-Johns Melting Point Apparatus.
- the determination of average molecular Weight as used herein is made by the Thermoelectric Differential Vapor Pressure Lowering Method on a Microlab Osmometer.
- the copolymer carboxylic acid reactant can be composed in part of monomeric carboxylic acid, for instance, the latter material may be as much as 80 molar percent of the total carboxylic acid reactant. When the monomeric acid is used it may be a minor molar amount of the total carboxylic acid reactant and is preferably at least about 5 molar percent of the total when employed.
- the monomeric carboxylic acid of the present invention may be a rnn0- or polycarboxylic acid including the corresponding acid anhydrides, esters or acid halides of the carboxylic acids.
- the acid can be straight chain or branched, saturatred or unsaturated, aliphatic (including cycloaliphatic), aromatic or heterocyclic.
- the monomeric carboxylic acids include, for instance, the monocarboxylic and polycarboxylic acids and their anhydrides, containing at least about 2, and often up to about 26 or more, carbon atoms.
- the preferred monomeric carboxylic acids are the aliphatic monoand dicarboxylic or alkanoic acids and anhydrides of 2 to about 21 carbon atoms.

- the amine component of the reaction product of the invention can be either a monoamine or a polyamine or both, for instance, each in an amount of at least about 0.05 mole per mole of reactive carboxylic acid group of the carboxylic acid reactant.
- the monoamine reactant of the invention includes those having the formula:
- R is a monovalent hydrocarbon radical, preferably alkyl, including cycloalkyl, of up to about 100 or more carbon atoms, preferably about to 25 carbon atoms, and R is R or hydrogen.

- more than one carboxylic acid or carboxylic acid anhydride may be reacted with one or more of the amines of the invention.
- the reactants can be reacted simultaneously, for instance, at about 125 to 350 C., preferably about 190 to 280 C.
- Various orders of addition of the reactants can be used, for example, a portion of the amine such as the monoamine can be reacted with the carboxylic acid and aminophenol and then the resulting intermediate reacted with the polyamine.
- Styrene-maleic anhydride resin-l-p-aminophenol with condensation product of an alkylsuccinic anhydride-polyamine
- the condensation products of this invention are characterized as either having at least one reactive phenolic hydroxy group which remains unsubstituted or is replaced with an alkaline metal.
- the oil-soluble alkaline metal salts, particularly the calcium salts, are effective for imparting thermal and oxidative stability to mineral oils.
- alkaline metal is meant the alkaline metals such as sodium, potassium and lithium and the alkaline earth metals such as calcium, barium and strontium.
- the alkaline salts can be prepared by neutralization of the condensation product with a basic compound of the alkaline metal as, for instance, the hydroxides, oxides, carbonates and the like or by neutralization with a metal oxide or hydroxide followed by preparation of the alkaline metal salt by metathesis.
- a basic compound of the alkaline metal as, for instance, the hydroxides, oxides, carbonates and the like or by neutralization with a metal oxide or hydroxide followed by preparation of the alkaline metal salt by metathesis.
- additional mineral oil of the type employed in preparing a mineral oil concentrate is added to the reaction mixture together with the basic compound and a small amount of Water to facilitate the neutralization.
- Greater than stoichiometric equivalents of the alkaline earth metals can be used, if desired, to give basic salts.
- the base oil into which the reaction product of the invention is incorporated can be of lubricating viscosity and can be a mineral oil or a synthetic oil.
- the mineral lubricating oils can be, for instance, solvent extracted or solvent refined oils obtained in accordance with conventional methods of solvent refining lubricating oils. Frequently, the viscosity of these mineral oils will be about to 250 SUS at 210 F.
- the mineral base oil may, for example, be derived from parafiinic naphthenic, as haltic or mixed base petroleum crudes, and if desired, a blend of solventtreated mid-continent neutrals and mid-continent bright stocks may be employed.
- Synthetic oils to which the reaction product may be added include ester-based synthetic oil of lubricating viscosity which consists essentially of carbon, hydrogen and oxygen, e.g., di-3-ethylhexyl sebacate.
- ester-based synthetic oil of lubricating viscosity which consists essentially of carbon, hydrogen and oxygen, e.g., di-3-ethylhexyl sebacate.
- Various of these lubricating materials have been described in the literature and generally their viscosity ranges from the light to heavy oils, e.g., about 50 SUS at 100 F. to 250 SUS at 210 F., and preferably to 150 SUS at 210 F.
- These esters are of improved thermal stability, low acid number and high flash and fire points.
- monoesters and polyesters may be used alone or to achieve the most desirable viscosity characteristics
- complex esters, diesters and polyesters may be blended with each CH CH 0 C in a other or with natural-occurring esters like castor oil to produce lubricating compositions of wide viscosity ranges which can be tailor-made to meet various specifications. This blending is performed, for example, by stirring together a quantity of diester and complex ester at an elevated temperature, altering the proportions of each component until the desired viscosity is reached.
- ester base oils are disclosed in US. Patents Nos. 2,499,983, 2,499,984, 2,575,195, 2,575,196, 2,703,811, 2,705,724, and 2,723,286.
