Abstract:
A process for producing phenyl-alkanes by paraffin dehydrogenation followed by olefin isomerization and then by alkylation of a phenyl compound by a lightly branched olefin is disclosed. An effluent of the alkylation section comprises paraffins that are recycled to the dehydrogenation step. A process that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups to produce modified alkylbenzene sulfonates is also disclosed. In addition, the compositions produced by these processes, which can comprise detergents, lubricants, and lubricant additives, are disclosed.

Abstract:
In a process for preparing an alkylaromatic hydrocarbon composition an olefinic hydrocarbon mixture and an aromatic compound are contacted under alkylation conditions with an aromatic alkylation catalyst selected from a homogeneous acid catalyst and heterogeneous acid catalyst comprising a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom. The olefinic hydrocarbon mixture comprises at least 5wt% by weight of mono-olefin oligomers of the empirical formula: C n H 2n wherein n is greater than or equal to 10, the mono olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C 1 -C 3 alkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

The present invention relates to an emulsifier composition suitable for mixing with oil to form lubricants comprising at least one non-extracted salt of a natural petroleum sulfonic acid having about 15 wt-% to about 30 wt-% active content; at least one branched chain alkylaryl sulfonic acid or salt thereof; at least one linear alkylaryl sulfonic acid or salt thereof; and optionally at least one other sulfonic acid or salt thereof for adjusting the average equivalent weight of the resultant emulsifier composition.
Abstract:
The invention relates to a method for producing diaryliodonium sulfonates in high yields and with a high degree of purity and then isolating the same, by reacting special diaryliodonium salts with an aliphatic or aromatic sulfonic acid or an alkaline, alkaline earth or ammonium salt of this sulfonic acid in the presence of water and one or more organic solvents which are immiscible or only slightly miscible with water.
Abstract:
Processes for making particularly branched, especially monomethyl-branched or nongeminal dimethyl-branched surfactants used in cleaning products; preferred processes comprising particular combinations of two or more adsorptive separation steps and, more preferably, particular alkylation steps; products of such processes, including certain modified alkylbenzenes, modified alkylbenzenesulfonate surfactants, and consumer cleaning products, especially laundry detergents, containing them. Preferred processes herein more specifically use specific, unconventional sequences of sorptive separation steps to secure certain branched hydrocarbon fractions which are used in further process steps as alkylating agents for arenes or for other useful surfactant-making purposes. Surprisingly, such fractions can even be derived from effluents from current linear alkylbenzene manufacture.
