Patent number: 4151173Abstract: This invention is directed to oil-soluble acylated-nitrogen compositions having demulsifying characteristics obtained by reacting at least one carboxylic acid or carboxylic acid-producing compound having at least 8 aliphatic carbon atoms with an effective amount of at least one high molecular weight polyoxyalkylene polyamine; said polyamine having an average molecular weight of at least about 200. The acylated-nitrogen compositions of this invention are particularly useful as additives for a variety of oleaginous materials including, for example, lubricating oils, hydraulic fluids, lubricants, fuels, e.g., gasoline, diesel fuels, etc.Type: GrantFiled: May 25, 1973Date of Patent: April 24, 1979Assignee: The Lubrizol CorporationInventor: Paul W.

Patent number: 4140643Abstract: Nitrogen- and sulfur-containing compositions are prepared by reacting an oil-soluble dispersant with a dimercaptothiadiazole such as 2,5-dimercapto-1,3,4-thiadiazole and subsequently reacting the intermediate thus formed with a carboxylic acid or anhydride containing up to about 10 carbon atoms and having at least one olefinic bond. The preferred carboxylic acid or anhydride is maleic anhydride. The compositions thus obtained are useful in lubricants as dispersants, extreme pressure agents, corrosion inhibitors and inhibitors of copper activity and "lead paint" deposition.Type: GrantFiled: June 3, 1977Date of Patent: February 20, 1979Assignee: The Lubrizol CorporationInventor: Kirk E.

Patent number: 4108783Abstract: Condensation products made by reacting an alphahaloalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The number of carbon atoms in the aromatic hydrocarbyl compound's substituents are each about 25 while the haloalkyl group contains from one to about 36 carbons. The acid or nitrile reactant usually contains three to about forty carbons. Product made from halomethyl alkyl-substituted phenols and .alpha.,.beta.-olefinic diacid derivatives such as maleic anhydride are particularly useful. Similarly useful products can be made from these condensation products by further reacting their acid, acid derivative or nitrile groups with alcohols, polyols, monoamines, polyamines, metal salts or metals.Type: GrantFiled: May 10, 1976Date of Patent: August 22, 1978Assignee: The Lubrizol CorporationInventor: David Eugene Ripple

Patent number: 4108784Abstract: Condensation products made by reacting an alpha-hydroxyalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The total number of carbon atoms in the non-fused hydrocarbyl substituents is at least about seven while the alpha-hydroxyalkyl group contains from one to about 36 carbons and the olefinic acid or nitrile reactant usually contains two to about forty carbon atoms. Products made from hydroxymethyl alkyl-substituted phenols and .alpha.,.beta.-olefinic acid derivatives such as maleic anhydride are particularly useful. Similarly useful post-treated products can be made from these condensation products by further reaction with alcohols, amines, metal salts or metals.Type: GrantFiled: April 19, 1976Date of Patent: August 22, 1978Assignee: The Lubrizol CorporationInventor: Charles Peterson Bryant

Patent number: 4098708Abstract: Esters of alkyl-substituted hydroxyaromatic carboxylic acids (especially alkyl-substituted salicylic acids) and the like, in which the alkyl substituent contains at least about 10 carbon atoms, are useful as dispersant additives for lubricants and fuels. Particularly useful are esters in which the substituent is derived from propylene, 1-butene or isobutene and has a molecular weight of about 150-1750, and in which the alkyl moiety is derived from pentaerythritol. Such esters are preferably prepared by the reaction of the corresponding organic hydroxy compound with a vic-hydroxyalkyl ester of the salicylic acid.Type: GrantFiled: June 16, 1975Date of Patent: July 4, 1978Assignee: The Lubrizol CorporationInventor: Carl Walter Stuebe
