三氯化铝是常用的烷烃异构化催化剂之一,但需要有少量的水存在,如果用无水三氯化铝,需要较高的反应温度.Ono等用等克分子的无水三氯化铝和无水硫酸铜的混合物作为催化剂,可以使正戊烷在较低的温度(28℃)下进行异构化反应,3小时后总转化率为21％,选择性为92％.但这种催化剂对于正己烷的异构化反应,活性很低,总转化率只有1％.何纪纲等制备了聚氯乙烯—三氯化铝·硫酸铜催化剂,证明它在15℃下能够催化正己烷的异构化反应,总转化率为25％,但选择性只有58％.
Aluminum trichloride is one of the commonly used alkane isomerization catalysts, but requires a small amount of water, if you use anhydrous aluminum trichloride, the need for higher reaction temperature .Ono such as molecularly anhydrous triclosan The mixture of aluminum oxide and anhydrous copper sulfate serves as a catalyst for the isomerization reaction of n-pentane at a lower temperature (28 ° C) with a total conversion of 21% and a selectivity of 92% after 3 hours This catalyst for the isomerization of n-hexane, activity is very low, the total conversion rate of only 1%. He Jigang et al prepared polyvinyl chloride - aluminum trichloride · copper sulfate catalyst that it can catalyze at 15 ℃ n The isomerization of the alkane gave a total conversion of 25% but a selectivity of only 58%.
