Изучены кинетические закономерности жидкофазного окисления циклогексанона в присутствии комплексов меди и кобальта со сшитыми полиэтилениминами и карбоксильной смолой. Установлено, что в присутствии комплекса меди со сшитым ПЭИ при 140 0 С скорость реакции увеличивается примерно на порядок. То же самое наблюдается в присутствии комплекса кобальта со сшитым ПЭИ. В случае использования в качестве носителя карбоксильной смолы КБ-4П2, каталитическая активность комплексов кобальта значительно выше комплексов, содержащих медь. Установлена оптимальная концентрация катализатора, увеличение которой приводит к ингибированию скорости реакции.
Kinetic regularities of catalytic liquid-phase oxidation of n-hexadecane in the presence of metal complexes of variable valence were studied. In the reaction of n-hexadecane oxidation as a catalytic mixture, a complex o-phenanthroline with stearate with variable valence metals (Mn2+, Cu2+, Co2+) was used. It found that o-phenanthroline significantly influences the catalytic activity of metal ions. The introduction of organic ligand into the catalytic system, as well as varying the ligand: metal salt ratio, has effect greatly on the course and character of the process.
The reactions of liquid-phase oxidation of aliphatic oxygen containing hydrocarbons, in particular, nonanol-4 and nonanon-4 in the presence of polyethylene-polyamine complexes (PEPA) with sorbated ions of metals with changeable valency (Co2+,Cu2+, Ni2+) were studied. It revealed that the oxidation of nonanole-4 and nonanone-4 in the presence of Cu2+ and Ni2+ ions in the analyzed system is less active while in the presence of Co2+ ions decarboxylation of acids it is practically absent and it leads mainly to formation of carbonic acids. It has been established that the character of oxidation reaction mostly depends on the properties of metals fixed on polymer matrix.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
