摘要

摘要研究了С16-С18馏分的α-烯烃中双键在具有褐铁矿型晶体结构的Y型沸石上的位置异构化。将催化剂的二氧化硅比率从 45 提高到 75，可生成凝固点较低的异构化烯烃。催化剂浓度、温度和工艺时间的增加不仅加速了双键迁移的目标反应，也加速了烯烃低聚的副反应。

Specific Features of Positional Isomerization of α-Olefins in the Presence of Zeolite Catalysts

The positional isomerization of the double bond in α-olefins of С₁₆–С₁₈ fraction on Y-type zeolite with the faujasite-type crystal structure in the H form was studied. An increase in the silica ratio of the catalyst from 45 to 75 leads to the formation of isomerized olefins with lower congealing points. An increase in the catalyst concentration, temperature, and process time leads to the acceleration not only of the target reaction of the double bond migration but also of the side reaction of olefin oligomerization.

期刊介绍： Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
