Definitions

  • ABSTRACT New lubricating oil additives comprising the reaction product of diphenylolpropane with an aliphatic chain substituted-succinic anhydride or acid. which aliphatic chain substituent is substantially saturated and contains at least about 30 carbon atoms. said reaction product being neutralized with an amine, preferably a polyamine, such as a polyalkylenepolyamine.
  • Lubricating oils, fuel oils, andoidss containing the new additives have excellent detergent, dispersing and anti-rust properties.
  • the present invention relates to new lubricating oil additives which impart to lubricating oils good detergent, dispersing and anti-rust properties. This invention relates also to lubricating oils and to fuels and carbura'nts containing said additives.
  • additives for lubricating oils which consist of derivatives of succinic acid or anhydride substituted with slightly unsaturated hydrocarbons.
  • This class of additives which has been known for some years, was an important development to the lubricating oil art. They consist mainly of reaction products of succinic acylating agents, substituted with a fairly saturated hydrocarbon radical containing an aliphatic chain of at least about 50 carbon atoms, with amines or alcohols.
  • Another object of the present invention is the provision of a lubricating oil additive having improved properties over those of the prior art alkyl substituted succinic esters described, for example, in U.S. Pat. No. 3,381,022 granted Apr. 30, 1968, and also with regard to the amide derivatives described in U.S. Pat. No. 3,172,892 of Mar. 9, 1965.
  • the lubricating oil additives of the present invention comprise reaction products of diphenylolpropane with an hydrocarbon chain substituted succinic anhydride or acid, which hydrocarbon chain substituent is substantially saturated and contains at least 30 and preferably at least 50, carbon atoms, said resulting product being then neutralized with a polyamine, such as a polyalkylenepolyamine.
  • the esterification reaction between the substituted succinic acid or anhydride and diphenylolpropane results in an equilibrium difficult to displace; the resulting product contains in solution a variable proportion of the unreacted succinic acylating agent and, as a dispersion in said solution, unreacted diphenylolpropane. It is essential, in order to obtain good dispersing properties when employing the product as a lubricating oil additive, to neutralize the unreacted acylating agent with an amino compound.
  • the unreacted diphenylolpropane may be removed, if it is in a large excess, by any convenient way such as filtration, centrifugation, etc.
  • the hydrocarbon chain-substituted succinic acid or anhydride starting materials used in the present invention are those resulting from the reaction ofmaleic acid or anhydride with a polyolefin, such as polyethylene, polypropylene, polybutylene, polyisobutylene, etc. having a molecular weight sufficient to provide a carbon content of at least about 30 atoms, preferably at least about 50 carbon atoms.
  • the hydrocarbon chain is preferably aliphatic in nature.
  • the molecular weight of such polyolefins is at least about 400. It is also possible to use a chlorinated polyolefin, such as chloropolyethylene, which is reacted with maleic acid or anhydride.
  • the reaction product is the polyolefin-substituted succinic anhydride.
  • the substantially saturated hydrocarbon substituent of the succinic radical may contain polar groups in minor proportions: chloro, nitro, etc. Hydrolysis of this product by water or steam treatment will produce the corresponding succinic acid.
  • the esterification reaction of diphenylolpropane with the aliphatic substituted succinic anhydride or acid may be achieved in the presence of a classical esterification catalyst, i.e., a base or acid, such as pyridine or its hydrochloride, sulfuric acid, para-toluenesulfonic acid and ion exchange resins having a strongly or moderately acid character. It may also be achieved without any catalyst.
  • This esterification reaction occurs preferably at a temperature from about 50 to 300C, preferably between about and 200C, with or without a solvent such as xylene, toluene, etc. The solvent simplifies both temperature control and water removal from the reaction mixture.
  • the relative proportions of the two constituents, diphenylolpropane and aliphatic substituted succinic acid or anhydride may vary within large limits. But in any event, since esterification is usually not complete, the remaining acid or anhydride must afterwards be neutralized with an aminated compound. Such neutralization is an important feature of the invention, as it is necessary to obtain good dispersing properties.
  • the unreacted diphenylolpropane, finely dispersed in the product resulting from the esterification reaction may be removed if it is in a substantial quantity. Otherwise it may remain in the product in a divided form without involving any disadvantage or incompatibility.
  • the esterification reaction involves a time duration of between about 1 and 10 hours, preferably 2 to 6 hours. It may occur under the normal atmospheric pressure, or under an elevated or reduced pressure, or in an atmosphere of inert gas.
  • EXAMPLE 1 2 kilograms of polyisobutylene substituted-succinic anhydride, prepared as hereinabove [Pibsa index 53 Pibsa index (for polyisobutenyl succinic anhydride) is the number of potash milligrams which are necessary for neutralizing 1 gram of product] were reacted with 107 grams of diphenylol propane in the presence of 21 grams of p-toluenesulfonic acid catalyst for 4 hours at a temperature of 160C. The product was then vaporized under vacuum at 160C. for 1 hour, and neutralized with 82 grams of tetraethylenepentamine at 155C. for 2 hours, under a partial vacuum (400 mm. Hg. pressure, approximately). This treatment was followed with a vaporization at mm. Hg. pressure for 30 minutes. Nitrogen content in the final product was 1.29%.
  • EXAMPLE 2 62.5 grams of diphenylolpropane were heated at 170C. 484 grams of polyisobutylene substitutedsuccinic acid prepared as hereinabove (Pibsa Index 63.5) were introduced over 15 minutes at 170C. under 400 mm. Hg. pressure. The reaction proceeded for 4 hours (170C. under partial vacuum). 543 grams of the resulting product were treated afterwards with 21.5 grams of tetraethylenepentamine under the same conditions as in Example 1. Nitrogen content in final product was 1.40%.
  • EXAMPLE 3 64 grams of diphenylolpropane were heated in the presence of 472 grams of xylene at 1 l0-115C. Then 1257 grams of polyisobutylene substituted-succinic anhydride prepared as hereinabove, (Pibsa Index 62.5 were introduced over a period of minutes. After 1 hour of reaction at 110115C., 13.2 grams ofpyridine were added. A second addition of an equal amount of pyridine was made after 2 hours of reaction. After 3.5 hours of reaction, the product is vapourized at 140C. under 20 mm. Hg. pressure for minutes.
  • EXAMPLE 4 200 grams ofthe product of Example 3 were neutralized with 5.6 grams of tetraethylene pentamine under the same conditions as in Example 1. Nitrogen content of the final product was 1%.
  • EXAMPLE 5 200 grams of the product of Example 3 were neutralized with 7.7 grams of triethylenetetramine under the same conditions as in Example 1. Nitrogen content of the final product was 1.42%.
  • EXAMPLE 7 The acylating agent employed in this example was the reaction product of maleic anhydride with a polyisobutene having a molecular weight equal to about 455, heated at a temperature between 190 and 240C. for 10 hours.
  • polyolefin substituted succinic anhydrides may be employed such as those of polyethylene, polypropylene and polypentene, etc.
  • the amine employed for neutralization may be diethylenetriamine or pentaethylenehexamine, etc.
  • the additive products of the invention are desirably employed in lubricating oils, fuel oils andoidss. in amounts of between about 0.01 and 10%, preferably between 0.1 and 3%, by weight of oil.
  • Example 1 product 308
  • Example 5 product 312 A comparison was made of the dispersing values obtained by the same test method with other products such as a non-neutralized ester and prior products commonly used,'considered as typical of the present state of the art. Listed below are the values obtained:
  • Example 3 (non-neutralized product) 200 Monosuccinimide 268 Bis succinimide 274 Ester of substituted succinic acid and pentaerythritol 265 Ester of substituted succinic acid and glycerol 250 Ester of substituted succinic acid and phenol MONOSUCCINIMIDE PREPARATION 250' grams of polyisobutylene substituted-succinic anhydride having a Pibsa index 53 were reacted with 18 grams of tetraethylenepentamine at 155C. for 2 hours, under partial vacuum (about 400 mm. Hg. pressure). Treatment was followed with a vapourization under 20 mm. Hg. pressure for minutes. Nitrogen content of the final product was 2.46%.
  • the anti-rust characteristics of the products according to the invention have been tested in the laboratory with favorable results.
  • the general tendency has been confirmed by motor tests (sequence II B, gasoline motor V-8 of a 1967 Oldsmobile).
  • the basic formulation to which the additive was added was composed of a calcium sulfonate, a calcium phenate and a zinc dithiophosphate.
  • An additive consisting of the ester reaction product of diphenylolpropane with an hydrocarbon substituted-succinic anhydride or acid, wherein the said hydrocarbon substituent is substantially saturated and contains at least about 30 carbon atoms, said reaction product being neutralized with a polyamine.
  • polyalkylenepolyamine is a member selected from the class consisting of diethylenetriamine, triethylenetetramine, tetraethylenepentamine and pentaethylenehexamine.
