离子液体Et 3 NHCl-2AlCl 3能有效催化正戊烷异构化反应。随着正戊烷转化率的增加,异构化油的研究法辛烷值增加,异构化油的收率、异戊烷选择性和异构化产物的研究法辛烷值降低。在相同的正戊烷转化率下,低反应温度抑制副反应并有利于产物分布。研究了正戊烷异构化消失动力学,其动力学符合一级反应。表观活化能和指前因子分别为29.4kJ/mol和9.28s-1。
The ionic liquid Et3NHCl-2AlCl3effectively catalyzes the isomerization of n-pentane. With increasing n-pentane conversion, the research octane number of isomerization oil increased, but its yield, the selectivity of isopentane, and the research octane number of the isomerization product decreased. At the same n-pentane conversion, low reaction temperatures inhibit side reactions and favor the product distribution. The disappearance kinetics of n-pentane isomerization, following the first-order reaction, was investigated. The apparent activation energy and the pre-exponential factor were 29.4kJ/mol and 9.28s−1, respectively.
