An oil-soluble lubricating oil additive composition prepared by the process which comprises reacting (A) reacting a copolymer of an (i) an unsaturated acidic reagent; and (ii) a mono-olefin, with at least one linking hydrocarbyl di-primary amine, thereby producing a hybrid succinic anhydride copolymer having from about 10% to about 90% unreacted anhydride groups; and subsequently (B) reacting the hybrid succinic anhydride copolymer with a second amine compound, thereby producing the succinimide; and (C) reacting the succinimide with at least one post-treating agent selected from a cyclic carbonate, a linear mono-carbonate, a linear poly-carbonate, an aromatic polycarboxylic acid, an aromatic polycarboxylic anhydride, an aromatic polycarboxylic acid ester, or mixtures thereof.

Post-treated additive composition and method of making the same

Disclosed is a process for preparing a molybdated succinimide complex, the process comprising: wherein R is an about Cto Calkyl or alkenyl group, R' is a straight or branched-chain alkylene group having 2 to 3 carbon atoms, x is 1 to 11, and y is 1 to 10, with an &#x3b1;,&#x3b2;-unsaturated mono-carboxylic acid or carboxylic acid ester, in a charge mole ratio of the &#x3b1;,&#x3b2;-unsaturated mono-carboxylic acid or carboxylic acid ester to the succinimide of formula I or formula II or mixtures thereof of about 0.1:1 to about 6:1, and wherein the reaction temperature is no greater than about 135&#xb0; C.; and

Process for preparation of low molecular weight molybdenum succinimide complexes

Disclosed is a process for preparing a molybdated succinimide complex, the process comprising: wherein R is an alkyl or alkenyl group having a number average molecular weight of about 500 to about 5,000, R' is a straight or branched-chain alkylene group having 2 to 3 carbon atoms, x is 2 to 11, and y is 1 to 10, with an &#x3b1;,&#x3b2;-unsaturated mono-carboxylic acid or carboxylic acid ester, in a charge mole ratio of the &#x3b1;,&#x3b2;-unsaturated mono-carboxylic acid or carboxylic acid ester to the succinimide of formula I or formula II or mixtures thereof of greater than 1.05:1 to about 6:1, and wherein the reaction temperature is in the range of from greater than 80&#xb0; C. to no greater than about 150&#xb0; C.; and

Process for preparation of high molecular weight molybdenum succinimide complexes

A method for reducing halide concentration in a hydrocarbon product having an organic halide content from 50 to 4000 ppm which is made by a hydrocarbon conversion process using an ionic liquid catalyst comprising a halogen-containing acidic ionic liquid comprising contacting at least a portion of the hydrocarbon product with at least one molecular sieve having pore size from 4 to 16 Angstrom under organic halide absorption conditions to reduce the halogen concentration in the hydrocarbon product to less than 40 ppm is disclosed.
