Abstract

A lubricating oil detergent composition comprises an overbased calcium sulfonate and a low ash detergent, which low ash detergent is metal free and comprises the reaction product of an acidic organic compound such as an alkylated salicylic acid, a boron compound and an amine component.

First claim

What is claimed:

1 . A detergent composition for lubricants and fuels comprising an overbased calcium sulfonate and a low ash detergent, wherein the low ash detergent is present in an amount of from 1 to 20 wt %, based on the weight of the combination of overbased calcium sulfonate and low ash detergent, which low ash detergent comprises the reaction product of one or more acidic organic compound, one or more boron compound and an amine component comprising one or more amine, and which low ash detergent contains no metals, phosphorus or sulfur,
wherein the one or more acidic organic compound is one or more carboxylic acids selected from the group consisting of
substituted salicylic acids of formula I:

wherein R 1 is independently a hydrocarbyl group having from 1 to about 30 carbon atoms, and ‘a’ is an integer of 1 or 2;
acids of formula

wherein X and X′ are independently hydrogen, hydrocarbyl, and halogen, R 13 is polymethylene or branched or unbranched alkylene, x is 0 or 1 and R 14 is hydrogen or hydrocarbyl;
acids of formula

wherein R 15 and R 16 are independently selected from the group consisting of hydrogen, alkyl groups, and aralkyl groups, provided that both R 15 and R 16 are not hydrogen, each R 17 are independently selected from the group consisting of hydrogen, alkyl groups, aralkyl groups, and cycloalkyl groups, and x is from 0 to 24;
and salicylic acid calixarenes;

the boron compound is selected from the group consisting of boric acid, trialkyl borates, alkyl boric acids, dialkyl boric acids, boric oxide, boric acid complex, cycloalkyl boric acids, dicycloalkyl boric acids, diaryl boric acids, and substitution products of the foregoing with alkoxy groups, alkyl groups, alkyl groups;
and the amine component comprises one or more amine selected from the group consisting of alkoxylated amines, poly-alkyleneamines, poly-oxyalkyleneamines and poly-alkylphenoxyaminoalkanes.

2 . The detergent composition according to claim 1 , wherein the one or more carboxylic acid is selected from the group consisting of substituted salicylic acids of formula I.

3 . The detergent composition according to claim 2 wherein R1 is independently alkyl, alkenyl, cycloalkyl, cycloalkenyl, aromatic, aromatic substituted by aliphatic or aromatic having from 1 to about 30 carbon atoms, or said alkyl, alkenyl, cycloalkyl, cycloalkenyl, aromatic, aromatic substituted by aliphatic or aromatic substituted by halo or hydroxyl, or said alkyl, alkenyl, cycloalkyl or cycloalkenyl which contains in a chain otherwise composed of carbon a heteroatom selected from oxygen or nitrogen.

4 . The detergent composition according to claim 2 wherein R1 is independently a hydrocarbyl having from 1 to about 30 carbon atoms which is purely hydrocarbon.

5 . The detergent composition according to claim 2 , wherein the amine component further comprises one or more alkoxylated amides.

6 . The detergent composition according to claim 2 , wherein the one or more boron compound comprises boric acid.

7 . The detergent composition according to claim 5 , wherein the one or more boron compound comprises boric acid.

8 . A composition comprising an oil of lubricating viscosity and the detergent composition according to claim 1 .

9 . A composition comprising an oil of lubricating viscosity and the detergent composition according to claim 6 .

10 . A composition comprising an oil of lubricating viscosity and the detergent composition according to claim 7 .

11 . A composition comprising a fuel and the detergent composition according to claim 1 .

12 . A composition comprising a fuel and the detergent composition according to claim 6 .

13 . A composition comprising a fuel and the detergent composition according to claim 7 .
