N2 - In the alkylation of isobutane with 2-butene, the salient features of a good homogeneous catalyst and reaction media are the acid strength and the solubility of isobutane in the catalyst. The protonation of the olefins in the feed is dependent on the acidity of the catalyst, whereas the amount of the carbenium ions formed strongly depends on the solubility of isobutane. From this point of view, various 1-alkyl-3-methylimidazolium halides-aluminum halides [CnMIM]X-AlX3 (where n = 4, 6, and 8) were examined as a potential relatively benign catalyst for this reaction and results on activity and selectivity of the catalysts were presented. For sulfuric acid system, even though it showed very high activity initially, the olefin conversion quickly decreased with time on stream. Above 25°C, oligomerization of olefin became significant and the activity decreased with temperature. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
