  • Publication number: 20130225873
    Abstract: This invention concerns a promoted catalyst system for making one or more alkanols from synthesis gas. The catalyst system contains a ruthenium compound and a halogen promoter dispersed in a low-melting tetraorganophosphonium salt. The halogen promoter is a compound capable of generating HX (where X?Cl, Br, or I) under reaction conditions. The invention also concerns a process for selectively preparing one or more alkanols from synthesis gas using the promoted catalyst system.

  • Patent number: 8507405
    Abstract: The present invention is directed to compositions and processes for the production of stable, alkaline, high solids, low viscosity, low surface tension, low flammability, sub-micron titania sols that have minimal offensive odor and methods of their use. Compositions of the present invention include, for example, mixtures of strong and weak organic bases used as dispersants to stabilize the titania sols. The dispersant mixtures have been found to result in relatively high titania solids content, low surface tension, low viscosity suspensions that are low in flammability. Sols produced according to the present invention can be used, for example, in catalytic applications such as catalyst supports for diesel emission control, or in pollutant photocatalyst applications in which it is desirable to have the titania in sol form.
