    摘要: A reactor which comprises a vessel (1) with a vessel bottom (2), a stirrer (3) arranged in the vessel, an emergency discharge valve (4) arranged in the vessel bottom for emptying the reactor in less than 600 seconds and at least one filtration device (5) arranged in the vessel bottom is suitable for the safe preparation of organic peroxides. The process for preparing an organic peroxide comprises the steps of preparing a solid hydroperoxide in the form of a suspension in the reactor, filtering the suspension through the filtration device (5) arranged in the vessel bottom (2) while retaining the solid hydroperoxide in the reactor and reacting the hydroperoxide with an alkylating agent, an acylating agent or a carbonyl compound.

    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.
