WebMay 1, 2024 · The deuterated 2-butene was used to determine the alkylation reaction of isobutane and 2-butene in the composite ionic liquid ([BMIM]Cl-AlCl 3-CuCl, CIL). The alkylation reaction was investigated in a batch stirred reactor. The self-alkylation and the oligomerization of 2-butene are more likely to occur in the CIL.
