    Abstract: This invention is directed to detergent compositions which employ sulfonated linear alkylbenzenes as surfactants, wherein the sulfonated linear alkylbenzenes have a higher content of the sulfonated 2-phenyl alkylbenzene isomers than was previously available in sulfonated phenyl alkylbenzene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated linear alkylbenzenes having lower contents of the 2-phenyl alkylbenzene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkylbenzenes are also provided, including dry formulations containing same.

    Abstract: This invention is directed to a fluorine-containing mordenite catalyst and use thereof in the manufacture of alkylbenzene (LAB) by alkylation of benzene with an olefin. The olefin may have from about 10 to 14 carbons. The fluorine-containing mordenite is prepared typically by treatment with an aqueous hydrogen fluoride solution. The benzene alkylation may be conducted using reactive distillation. This invention is also directed to a process for production of LAB having a high 2-phenyl isomer content by use of the fluorine-containing mordenite in conjunction with a conventional solid LAB alkylation catalyst. The two catalysts may be used in a mixed catalyst bed or may be packed in series, with the relative proportions being adjusted to provide a desired 2-phenyl isomer content of in the final product.
