| Abstract：5-tertbutly-1,2,3-terimeth benzene was synthesized by the alkylation reaction of 190# solvent oil(containing 70%hemimetene)with isobutene(99.9%) at low temperature and anhydrous AlCl3 katalyst.The results of these experiments show that the optimum conditions are 4% catalyst,reaction temperature at 25 ℃,85L/h of velocity of flow of isobutene and reaction time for 35 min.99% production is obtained by decompression rectify.The yield of 5-tertbutly-1,2,3-terimeth benzene is 85%.The method has many advantages su... |
