摘要:
The present invention provides methods by which carbon nanotubes can be functionalized via Diels-Alder reactions under solvent free conditions. Such methods include reacting carbon nanotubes with Diels-Alder dienes or dienophiles to obtain adducts that includes the diene or dienophile moiety bound to the carbon nanotubes. Functionalized carbon nanotubes and dispersions containing functionalized carbon nanotubes are provided. The present invention provides functionalization methods of carbon nanotubes through gas phase, liquid phase, or solid phase reactions without any solvents other than the reactants. Such processes are also amenable to a wide variety of chemical reactions that use other functionalizing agents. Additionally, such methods are cost effective, easily scalable and can provide for functionalized CNTs in large, industrial-scale quantities.

The present invention provides a method for producing a silica composite by the steps of: preparing a raw material mixture containing silica and zeolite; drying the raw material mixture to obtain a dried product; and calcining the dried product, wherein the method comprising the step of allowing the raw material mixture to contain phosphoric acid and/or phosphate or bringing a solution of phosphoric acid and/or phosphate into contact with the zeolite and/or the dried product, or a combination thereof to thereby adjust a phosphorus content in the silica composite to 0.01 to 1.0% by mass based on the total mass of the silica composite.
摘要:
Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones, cyclic ethers and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, cyclic ethers, alcohols and/or ketones, by condensation and/or deoxygenation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, alcohols and/or ketones, by condensation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

摘要:
Aromatic alkenes, especially diarylbutadienes are produced in a simple economic process by reaction of an anil with an organic compound having a non-aromatic unsaturated system conjugated with an aromatic system, and a terminal methyl group pendent from the non-aromatic unsaturated system; in particular the organic compound is a propenyl-substituted aromatic compound.
摘要:
Aromatic compounds - either carbocyclic or heterocyclic - can be arylated by heating them with a nitro-substituted aromatic compound. Suitable reaction conditions include temperatures of about 400*-1000*C., pressures of about 0.01 to 1000 atmospheres, and a reaction time of 0.1 seconds to 10 hours. Also aromatic carbocyclic and aromatic heterocyclic compounds can be dimerized in the presence of nitro substituted aromatic compounds at similar reaction conditions.
