    摘要: The invention relates to a method for oxidizing substrates such as hydrocarbons, waxes or soot. The method involves the use of a compound of formula (I) in which: R1 and R2 represent H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 hydrocarbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 designate identical or different radicals or R1 and R2 can be linked to one another via a covalent bonding; Q1 and Q2 represent C, CH, N, CR5, each being the same or different; X and Z represent C, S, CH2, each being the same or different; Y represents O and OH; knull0, 1, 2; lnull0, 1, 2; mnull1 to 3, and; R5 represents one of the meanings of R1. Said compound is used as a catalyst in the presence of a radical initiator, whereby the molar ratio of the catalyst to the hydrocarbon is less than 10 mol %. Peroxy compounds or azo compounds can be used as the radical initiator. Preferred substrates are aliphatic or aromatic hydrocarbons.

    摘要: A process is provided for the production of formaldehyde from methyl chloride. In the process methyl chloride is oxidized with air over a catalyst to give formaldehyde and hydrogen chloride. In a preferred embodiment of the invention, a mixture of two different catalysts is used, one catalyst to promote the hydrolysis of methyl chloride to methyl alcohol, and the other catalyst to oxidize the methyl alcohol so formed to formaldehyde. The reaction kinetics can be regulated by adjusting the proportion of the two catalysts in the mixture. In this manner, the release of heat from the reaction can be controlled and excessive temperatures in the catalyst mixture can be avoided.

    摘要: A process of activating a fresh catalyst or regenerating a deactivated catalyst which is used in a hydro-oxidation process, preferably, the hydro-oxidation of an olefin in the presence of oxygen and hydrogen to an olefin oxide. The hydro-oxidation catalyst preferably comprises at least one metal selected from gold, silver, the platinum group metals, the lanthanide metals, and combinations thereof, incorporated onto a titanium- , vanadium- , or zirconium-containing support more preferably, a titanium-containing support, such as titanium oxide or a titanosilicate. The activation or regeneration process involves contacting the fresh catalyst or the deactivated catalyst with ozone.
