摘要： A chemical softening composition includes a amide-substituted quaternary imidazolinium salt, a nonionic surfactant, and a polyhydroxy compound for use in treating cellulosic materials including papers, textiles and fabrics. The chemical softening composition can be applied to papermaking fibers during a papermaking process to provide a softened paper web and product possessed of sufficient tensile strength for its regular employment. A chemical softening composition according to the invention can also be applied to fabric to soften the fabric, provide easier handling of the fabric, and also reduce the tendency of the fabric to generate and store static electricity.

摘要： 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.

摘要： 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.

摘要： A process for producing cyclohexane by benzene hydrogenation using a hydrogen source that contains impurities, such as carbon monoxide and/or light hydrocarbons, wherein a supported catalyst reduces benzene to cyclohexane and carbon monoxide to methane and water. Alkenes, such as ethylene, are also reduced to their alkane counterparts. Under the disclosed operating conditions, the process proceeds without deactivation of the catalyst, and without the formation of a significant amount of cracking products, such as methylcyclopentane.
