Abstract
Catalytic effect of ionic liquids to isobutane and butene alkylate reaction was studied,composition of ionic liquids,isobutane and butene mole compares factors to the alkylate reaction influence was reviewed.The result indicated that ionic liquid of AlCl3 mole score 0.65～0.70 is better to alkylate reaction,the AlCl3 content excessively low is advantageous to the alkene polymerization and excessively high is advantageous to the depth alkylate reaction in the ionic liquid,the butene conversion rate may achieve 100 % under 10～25 ℃ and the isobutane to the butene quality ratio more than 2.5.
