Oil soluble dispersant additives useful in oleaginous compositions
First Claim
1. An oil soluble composition dispersant useful as a dispersant additive for lubricating composition comprising the reaction products of:
- (1) at least one nitrogen containing adduct selected from the group consisting of (i) Mannich condensation product formed by condensing a long chain hydrocarbyl substituted hydroxy aromatic compound with aldehyde and a polyalkylene polyamine; and
(ii) Mannich condensation product formed by reacting long chain hydrocarbyl substituted mono or dicarboxylic acid or its anhydride with amine containing hydroxy aromatic compound, which may be optionally hydrocarbyl substituted, to form long chain hydrocarbyl substituted amide or imide-containing hydroxy aromatic compound intermediate adduct, and condensing said long chain hydrocarbyl substituted amide or imide-containing hydroxy aromatic compound adduct with aldehyde and polyamine;
said adduct containing at least one reactive group selected from reactive amino groups and reactive hydroxyl groups; and
(2) at least one polyepoxide.

Abstract
An oil soluble dispersant comprising the reaction products of:
(1) oil soluble salts, amides, imides, oxazolines, esters, or mixtures thereof of long chain hydrocarbyl substituted mono- and dicarboxylic acids or their anhydrides; (ii) long chain hydrocarbon having a polyamine attached directly thereto; (iii) Mannich condensation product formed by condensing a long chain hydrocarbyl substituted hydroxy aromatic compound with an aldehyde and a polyalkylene polyamine; and (iv) Mannich condensation product formed by reacting long chain hydrocarbyl substituted mono or dicarboxylic acids or their anhydrides with an aminophenol, which may be optionally hydrocarbyl substituted, to form a long chain hydrocarbyl substituted amide or imide-containing phenol intermediate adduct, and condensing said long chain hydrocarbyl substituted amide or imide-containing phenol adduct with aldehyde and polyamine; said adduct containing at least one reactive group selected from reactive amino groups and reactive hydroxyl groups; and
(2) at least one polyepoxide.

13. A lubricating composition comprising:
-
(A) major amount of a lubricating oil; and (B) a minor amount of an oil soluble dispersant which is effective to impart enhanced dispersancy comprising the reaction product of (1) at least one nitrogen containing adduct selected from the group consisting of (i) Mannich condensation product formed by condensing a long chain hydrocarbyl substituted hydroxy aromatic compound with aldehyde and polyamine; and
(ii) Mannich condensation product formed by reacting long chain hydrocarbyl substituted mono or dicarboxylic acid or its anhydride with amine substituted hydroxy aromatic compound, which may be optionally hydrocarbyl substituted, to form long chain hydrocarbyl substituted amide or imide-containing hydroxy aromatic intermediate adduct, and condensing said long chain hydrocarbyl substituted amide or imide-containing hydroxy aromatic adduct with aldehyde and polyamine;
said adduct containing at least one reactive group selected from reactive amino groups and reactive hydroxyl groups, and(2) at least one polyepoxide. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
