摘要:
The invention relates to a process of producing a carbonyl compound by dehydrogenating a linear aliphatic alcohol of 1 to 6 carbon atoms in the gas phase in the presence of a solid catalyst comprising a ruthenium catalyst supported on a carrier such as zinc oxide or magnesium oxide.
摘要:
This invention consists essentially in a method of removing oxygen from a gas containing an unsaturated hydrocarbon, which comprises contacting a gas containing an unsaturated hydrocarbon and oxygen with silver and/or gold, or a catalyst containing at least one of them, in the presence of hydrogen.
摘要:
A method of preparing a catalyst for the diacyloxylation of conjugated dienes such as butadiene by reaction with a carboxylic acid such as acetic acid and oxygen, which comprises separately and successively impregnating a carrier, for example carbon, with a solution of a Group VIII noble metal in a mixture of a mineral acid and an organic solvent, then with a solution of a Group IVA, VA or VIA element or compound thereof in an organic solvent.
摘要:
A novel intercalation compound is provided, in which compound monohydric alcohol is intercalated between layers of a layered compound comprising vanadium, phosphorus and oxygen as primary components, characterized in that the monohydric alcohol is aliphatic secondary monohydric alcohol, alicyclic monohydric alcohol, or aromatic monohydric alcohol. By heating the intercalation compound, a vanadium-phosphorus mixed oxide having a BET specific surface area of at least 80 m2/g can be obtained.
