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; k=0, 1, 2; l=0, 1, 2; m=1 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.
该发明涉及一种氧化底物(如烃、蜡或烟尘)的方法。该方法涉及使用式(I)的化合物,其中:R1和R2代表H、脂肪或芳香烷氧基基、羧基、烷氧羰基基或烃基,每个基有1到20个碳氢原子,SO3H、NH2、OH、F、Cl、Br、I和/或NO2,其中R1和R2表示相同或不同的基团,或者R1和R2可以通过共价键相连;Q1和Q2代表C、CH、N、CR5,每个基相同或不同;X和Z代表C、S、CH2,每个基相同或不同;Y代表O和OH;k=0、1、2;l=0、1、2;m=1到3;R5代表R1的一种含义。所述化合物作为催化剂在自由基引发剂存在下使用,其中催化剂与烃的摩尔比小于10mol%。过氧化物或偶氮化合物可用作自由基引发剂。首选底物为脂肪或芳香烃。
