Abstract:
In an embodiment, a method for converting an alkane to an alkyl alcohol comprises, co-currently flowing the alkane, a halogen source, and a catalyst, through a halogenation reactor to form a halogenated stream and a spent catalyst stream; directing the halogenated stream and a water stream to a second hydroxylation reactor end of a hydroxylation reactor; directing the spent catalyst stream to a first hydroxylation reactor end of the hydroxylation reactor, and counter-currently flowing the halogenated stream and the spent catalyst stream through the hydroxylation reactor to form a regenerated catalyst stream comprising the catalyst and a product stream comprising the alkyl alcohol and a hydrogen halide; and directing the regenerated catalyst stream comprising the catalyst back into the halogenation reactor.
Abstract:
A process for treating a composition comprising one or more desired (hydro)halocarbons and one or more undesired halogenated hydrocarbon containing impurities so as to reduce the concentration of at least one undesired halogenated hydrocarbon containing impurity, the process comprising contacting the composition with an adsorbent comprising a carbon molecular sieve.
Abstract:
Cavitand compositions that comprise void spaces are disclosed. The void spaces may be empty, which means that voids are free of guest molecules or atoms, or the void spaces may comprise guest molecules or atoms that are normally in their gas phase at standard temperature and pressure. These cavitands may be useful for industrial applications, such as the separation or storage of gasses. Novel cavitand compounds are also disclosed.
Abstract:
Die Erfindung betrifft ein verbessertes Verfahren zur technischen Herstellung von Diethylphosphit und Ethylchlorid, bei dem das Ausgangsmaterial Ethanol mit verfahrensspezifischen Zusatzstoffen vermischt und dieses Gemisch mit Phosphortrichlorid zur Reaktion gebracht wird. Das anfallende Koppelprodukt Ethylchlorid wird isoliert und findet Verwendung auf Grund der erzielten Reinheit.
Abstract:
Solid acidic or metal catalyst-promoted halogenation of methane to produce methyl monohalides in high selectivity. Concurrent or simultaneous hydrolysis provides methyl alcohol and/or dimethyl ether in good yields.
Abstract:
The present invention provides processes for the production of chlorinated methanes via the direct chlorination of methane. The processes include a dehydrochlorination and/or chlorination step that converts up to 100% of the higher chlorinated alkanes in a process stream from the methane chlorination reaction into more highly chlorinated alkanes. These more highly chlorinated alkanes can be easily removed from the process stream. The use of a cost effective feedstream of crude methane is thus rendered possible, without additional capital expenditure for the sophisticated separation equipment required to separate ethane and other hydrocarbon components from the methane feed.
Abstract:
Embodiments of the present disclosure provide for methods of hydrocarbon functionalization, methods and systems for converting a hydrocarbon into a compound including at least one group ((e.g., hydroxyl group) (e.g., methane to methanol)), functionalized hydrocarbons, and the like.
Abstract:
The present invention relates to a method for preparing chlorinated compounds from saturated hydrocarbon. More particularly, the present invention relates to the method for preparing chlorinated compounds by conducting alternately an oxidation reaction of a catalyst under oxygen and hydrogen chloride, and a chlorination reaction for converting the saturated hydrocarbon into the chlorinated compounds by using the catalyst. The present invention has the advantages that the conversion rate of the saturated hydrocarbon may be enhanced; there is no need to consider erexplosion hazards; unreacted hydrogen chloride and corrosion of reactor may be reduced; a separate device for separating COx in exhaust gases may not be required since CO or CO2 is not produced in a combustion reaction; by-product may not be generated; and the durability of a catalyst may be remarkably enhanced.
Abstract:
A process is provided for the chlorination of ethane using hydrogen chloride, chlorine or mixtures as the chlorination agent. The process includes reaction steps operated in tandem in separate zones first comprising the reaction of perchloroethylene with hydrogen chloride and oxygen in the presence of an oxychlorination catalyst to give hexachloroethane and water, and second comprising the vapor phase reaction of hexachloroethane with ethane feedstock to produce chlorinated ethanes, chlorinated ethylenes, and hydrogen chloride.
