Abstract:
The present invention provides a catalyst for hydrogenation of aromatic compounds, which comprises a hydrophilic support material; and a stationary aqueous acid phase supported by the hydrophilic support material, the aqueous acid having a transition metal catalyst dissolved therein. Preferably, the solid hydrophilic support material is an acidic material, such as an acid-treated clay. The foregoing catalyst is particularly useful in hydrogenating aromatic hydrocarbons.
Abstract:
A process is described for functionalizing a copolymer comprising units derived from at least one α-olefin and units derived from at least one diene, which copolymer contains at least one double bond. The process comprises reacting the copolymer with at least one functionalizing agent to introduce polar pendant oxygen-containing functional groups onto the copolymer.
Abstract:
The invention relates to a catalyst composition, a method of making the same and its use in a process for converting synthesis gas to alcohols. The catalyst composition comprises an anionic clay hydrotalcite and a catalytically active metal component, such as rhodium, manganese, cobalt, copper, and a mixture thereof.
Abstract:
The invention relates to a method of forming carbon monoxide-containing polymers from multi-component syngas feeds and at least one vinyl comonomer. Feeds useful in the practice of the invention comprise ethylene in an amount ranging from about 5 to about 40 mole %, carbon monoxide is an amount ranging from about 1 to about 40 mole %, hydrogen in an amount ranging from about 4 to about 55 mole %, carbon dioxide in an amount ranging from about 3 to about 10 mole %, and methane in an amount ranging from about 4 to about 85 mole %. The feed may also include acetylene in an amount ranging up to about 10 mole %. The feed may contain at least one free radical-polymerizable vinyl comonomer, or a cofeed containing such a comonomer can be used.
Abstract:
The invention is related to non-linear, paraffin-soluble olefin/carbon monoxide and olefin/acetylene/carbon monoxide copolymers. The invention is also related to a method for preparing olefin/carbon monoxide copolymers by heating a feed of at least one olefin, carbon monoxide, carbon dioxide, hydrogen, and methane in the presence of a free radical polymerization initiator. More particularly, the feed comprises at least one olefin, the total olefin amount ranging from about 5 to about 40 mole %, carbon monoxide in an amount ranging from about 1 to about 40 mole %, hydrogen in an amount ranging from about 4 to about 55 mole %, carbon dioxide in an amount ranging from about 3 to about 10 mole %, and methane in an amount ranging from about 4 to about 85 mole %. The feed may also include acetylene in an amount ranging up to about mole %.
