Abstract: A catalyst composition includes a metal catalyst dispersed in a molten eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides. A process for the catalytic cracking of hydrocarbons includes contacting in a reactor system a carbon-containing feedstock with at least one catalyst in the presence of oxygen to generate olefinic and/or aromatic compounds; and collecting the olefinic and/or aromatic compounds; wherein: the at least one catalyst includes a metal catalyst dispersed in a molten eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides. A process for preparing the catalyst includes mixing metal catalyst precursors selected from transition metal compounds and rare-earth metal compounds and a eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides and heating it. A use of the catalyst in the catalytic cracking process of hydrocarbons.

Abstract: The invention relates to a free-radical initiator composition for polyolefin modification comprising a peroxide-modified inorganic solid particle prepared from: i) a liquid or solution of hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a method for preparing a peroxide-modified inorganic composition, comprising mixing a liquid or solution of hydrogen peroxide and one or more inorganic solid particles to form a suspension or gel, and optionally, filtering the suspension or gel and drying the filtered materials to form a solid, peroxide-modified inorganic composition.

Abstract: A method is useful for preparing alkylalkoxysilanes, such as alkylalkoxysilanes, particularly dimethyldimethoxysilane. The method includes heating at a temperature of 150° C. to 400° C., ingredients including an alkyl ether and carbon dioxide, and a source of silicon and catalyst. The carbon dioxide eliminates the need to add halogenated compounds during the method.

Abstract: A method for making long chain hydroxyl terminated polydiorganosiloxanes with low cyclics content via condensation polymerization employs a selective catalyst. The catalyst includes a salt-anion complex and a free acid.
