摘要
有 1 的甲苯的完化，生产戊基甲苯的 3-pentadiene 被执行获得 2， 6-dimethylnaphalene，在 2 的生产期间是重要中介， 6 萘二羟基的酸。作为催化剂用无水的 AlCl3 基于我们的以前的工作，[bupy ] BF4-AlCl3 离子的液体被采用催化 1 的反应，有甲苯的 3-pentadiene。试验性的结果显示出那[bupy ] 当时， BF4-AlCl3 离子的液体特别对反应合适 AlCl3 到的臼齿的比率[bupy ] BF4 是 1.75：1，并且反应能在象 0 ° C 一样低的温度继续。它能象纯 AlCl3，而是更多环境联盟者一样活跃友好。
The alkylation of toluene with 1,3-pentadiene to produce pentyltoluene was carded out to obtain 2,6-dimethylnaphalene, which is an important intermediate during the production of 2,6-naphthalene dicarboxylic acid. Based on our previous work using anhydrous AlCl3 as catalyst, [bupy]BF4-AlCl3 ionic liquids were employed to catalyze the reaction of 1,3-pentadiene with toluene. The experimental results show that [bupy]BF4-AlCl3 ionic liquids are suitable for the reaction especially when the molar ratio of AlCl3 to [bupy]BF4 is 1.75 ： 1, and the reaction could proceed at the temperature as low as 0℃. It could be as active as pure AlCl3, but much more environmentally friendly.
