Abstract:
A process comprising: a) hydrogenating an aromatic compound comprising an aromatic ring and a substitutable hydrogen atom on said aromatic ring to form optionally substituted cyclohexene; b) contacting the cyclohexene with an oxidant under conditions effective to form cyclohexanone and unreacted cyclohexene; c) separating the cyclohexanone from the unreacted cyclohexene; and d) contacting at least a portion of the cyclohexanone with nitric acid and a conversion catalyst to produce adipic acid and nitrous oxide.

Abstract:
The invention relates to a method for carrying out a metathesis reaction of unsaturated organic compounds, characterized in that at least one unsaturated organic compound in a liquid or dissolved form is mixed with at least one metathesis catalyst in a liquid or dissolved form in at least one microreactor, allowed to react during a predetermined dwelling time and the organic compound produced is optionally isolated from the reaction mixture.
Abstract:
A catalyst composition and process for preparing such catalyst composition which can be useful in contacting a hydrocarbon-containing fluid which contains a highly unsaturated hydrocarbon such as 1,3-butadiene, in the presence of hydrogen, with such catalyst composition in a hydrogenation zone under a hydrogenation condition effective to hydrogenate such highly unsaturated hydrocarbon to a less unsaturated hydrocarbon such as n-butene is disclosed. Such process for preparing a catalyst composition includes (1) combining a zeolite, a Group VIB metal, and an inorganic support to form a modified zeolite; (2) calcining such modified zeolite under a calcining condition to produce a calcined, modified zeolite; and (3) contacting such calcined, modified zeolite with a carburizing agent under a carburizing condition to provide such catalyst composition.
Abstract:
A catalyst composition that is formed by combining (a)(i) an iron compound and a halogen-containing compound or (ii) a halogen-containing iron compound, (b) a hydrogen phosphite, and (c) an organoaluminum compound. This catalyst composition is particularly useful for preparing oligomers of conjugated dienes.
Abstract:
Catalytic complexes including a metal atom having anionic ligands, at least one nucleophilic carbene ligand, and an alkylidene, vinylidene, or allenylidene ligand. The complexes are highly stable to air, moisture and thermal degradation. The complexes are designed to efficiently carry out a variety of olefin metathesis reactions.
Abstract:
The present disclosure provides processes to convert heavy hydrocarbons to light distillates. The present disclosure further provides compositions including light distillates. In an embodiment, a process for upgrading a hydrocarbon feed includes dehydrogenating a C 3 -C 50 cyclic alkane and an C 2 -C 50 acyclic alkane in the presence of a dehydrogenation catalyst to form a C 3 -C 50 cyclic olefin and a C 2 -C 50 acyclic olefin. The process includes reacting the C 3 -C 50 cyclic olefin and the C 2 -C 50 acyclic olefin in the presence of a group 6 or group 8 transition metal catalysts to form a C 5 -C 200 olefin. The process further includes hydrogenating the C 5 -C 200 olefin in the presence of a hydrogenation catalyst to form a C 5 -C 200 hydrogenated product. Processes of the present disclosure may further include hydroisomerizing the C 5 -C 200 hydrogenated product in the presence of a hydroisomerization catalyst to form a C 5 -C 200 hydroisomerized product.
