对由杂多酸 醋酸组成的新型液体催化剂异丁烷/丁烯烷基化的活性相进行了研究.确定了催化活性相的组成,对活性相进行分离并采用FTIR、UV和NMR等方法对活性相进行表征.在此基础上提出了形成质子化杂多酸为起始步骤的烷基化反应机理,得到了实验结果的证明.
A new type of liquid catalyst consisting of heteropolyacid acetic acid was used to study the isobutane / butene alkylation of the active phase. The composition of the catalytically active phase was determined. The active phase was separated and analyzed by FTIR, UV and NMR Active phase characterization.On the basis of this, the alkylation reaction mechanism of protonated heteropoly acid as the starting step is proposed, and the experimental results prove.
