Abstract
It was supposed that, in the reaction of oxyethylation of alcohols, the kinetically independent unit is not a monomeric alcohol molecule, but a linear chain alcohol associate consisting of an average of n alcohol molecules, and that the reaction rate is of the first order not in the total concentration of all alcohol species, but in the concentration of these associates. The kinetic aspects of this phenomenon were considered. It was assumed that reactions of the first order in the concentration of an associated component, which are widespread in liquid-phase chemical kinetics, occur as a result of the release of the reaction product from the associate.
摘要 假定在醇的氧乙基化反应中，动力学上独立的单元不是单体醇分子，而是由平均 n 个醇分子组成的线性链醇缔合体，反应速率不是在所有醇种类的总浓度中，而是在这些缔合体的浓度中呈一阶。对这一现象的动力学方面进行了研究。我们假定，在液相化学动力学中普遍存在的伴生组分浓度一阶反应，是由于反应产物从伴生组分中释放出来而发生的。
期刊介绍：
Kinetics and Catalysis Russian is a periodical that publishes theoretical and experimental works on homogeneous and heterogeneous kinetics and catalysis. Other topics include the mechanism and kinetics of noncatalytic processes in gaseous, liquid, and solid phases, quantum chemical calculations in kinetics and catalysis, methods of studying catalytic processes and catalysts, the chemistry of catalysts and adsorbent surfaces, the structure and physicochemical properties of catalysts, preparation and poisoning of catalysts, macrokinetics, and computer simulations in catalysis. The journal also publishes review articles on contemporary problems in kinetics and catalysis. The journal welcomes manuscripts from all countries in the English or Russian language.
