在异丁烷/丁烯烷基化反应中研究了一种由杂多酸和醋酸组成的新型液体酸催化剂的催化性能,醋酸作为溶剂对杂多酸具有共协效应,系统研究了形成活性相的条件,杂多酸结晶水含量对活性相的形成和催化活性均有显著影响,这一催化体系具有与硫酸可比的催化活性.
In the isobutane / butene alkylation reaction, a new type of liquid acid catalyst consisting of heteropoly acid and acetic acid was studied. Acetic acid as a solvent has a synergistic effect on heteropolyacids. The effect of forming active phase The heteropoly acid crystal water content has a significant effect on the formation of the active phase and the catalytic activity. This catalytic system has comparable catalytic activity to sulfuric acid.
