Provided are formulations, methods of making, and methods of using a functional fluid of the present invention to achieve and maintain optimal frictional characteristics in machines housing that fluid, wherein the functional fluid comprises, among others, a friction-modifying amount of an alkyl toluene sulfonate salt or a mixture of alkyl toluene sulfonate salts.

Functional fluids comprising alkyl toluene sulfonates

Disclosed is a method for improving filtration in the preparation of an alkaline earth metal alkyltoluene sulfonate concentrate by selectively controlling the meta, ortho, para isomer distribution of the alkyl group of the alkyltoluene produced by the process comprising alkylating toluene with at least one isomerized normal alpha olefin, having from about 18 to about 30 carbon atoms and having from 20% to 100% branching in an alkylation process which includes monitoring % isomer formation and adjusting an alkylation process parameter in order to provide a target specified isomer content of less than 38% meta-isomer content; and thereafter sulfonating and neutralizing to produce a low base number sulfonated alkyltoluene concentrate having a Base Number of about 2 to 60 (ASTM D 2896).

Method for the preparation of low overbased alkyltoluene sulfonate

Provided is a lubricating oil composition comprising: (a) a major amount of an oil of lubricating viscosity; and (b) one or more borated alkaline earth metal alkyltoluene sulfonate detergents; wherein the lubricating oil composition comprises no more than about 0.20 wt. % of phosphorus and no more than about 0.50 wt. % of sulfur.

Lubricating oil with enhanced protection against wear and corrosion

Disclosed are detergent mixtures of alkyl aryl sulfonates of alkaline earth metals derived from linear olefins having a relatively high aryl ring attached on positions 1 or 2 or the linear alkyl chains. The compositions contain a relatively high amount of 1 or 2 tolyl or xylyl isomer of the linear alkylaryl sulfonate and employ a heavy alkyl benzene sulfonate derived from linear olefins and exhibit improved stability and compatibility.

Alkylaryl sulfonate detergent mixture derived from linear olefins

An alkaline earth metal borated sulfonate prepared by a process comprising reacting a mixture of the following materials (A) (1) at least one of an oil soluble sulfonic acid or alkaline earth sulfonate salt or mixtures thereof (2) at least one source of an alkaline earth metal; and (3) at least one source of boron, in the presence of a mixture of comprising (4) at least one hydrocarbon solvent; and (5) at least one low molecular weight alcohol; and (6) from 0 to less than 10 mole percent, relative to the source of boron, of an overbasing acid, other than the source of boron; and (B) heating the reaction product of (A) to a temperature above the distillation temperatures of (4) and (5) to distill (4), (5) and water of reaction, wherein no additional water is added in the process.

Process for making alkaline earth metal borated sulfonates

Provided is a new and improved process for preparing a borated alkaline earth metal toluene sulfonate salt.

The present invention is directed to novel alkylated aromatic compositions, zeolite catalyst compositions and processes for making the same. The catalyst compositions comprise zeolite Y and mordenite zeolite having a controlled macropore structure. The present invention is also directed to the preparation of the catalyst compositions and their use in the preparation of novel alkylated aromatic compositions. The catalyst compositions of the present invention exhibit reduced deactivation rates during the alkylation process, thereby increasing the life of the catalysts.

Alkylated aromatic compositions, zeolite catalyst compositions and processes for making the same

The present invention is directed to a zeolite Y catalyst having a controlled macropore structure. The present invention is also directed to a zeolite Y catalyst composite and a process for preparing the catalyst composite. The catalyst composite exhibits reduced deactivation rates during the alkylation process, thereby increasing the life of the catalyst. The present invention is also directed to processes for the preparation of carbonated, overbased aromatic sulfonates, which processes comprise alkylation, carbonation of aromatic hydrocarbons with one or more olefins.
