铝化

Nsted acid ionic liquids were inactive for the alkylation of isobutane with butene.In contrast,the chloroaluminate ioni c liquids were very active for the alkylation.However,the qualities of the alkylate oils using chloroaluminate ionic liquids were unsatisfied and worse than that of the products in the industrial sulfuric acid process obviously.
