1-Methylimidazole → 1-Butyl-3-methylimidazolium chloride

Participants

Reaction Steps

The procedure of Example 1 was repeated with minor changes. 549 g of 1-chlorobutane and 487 g of 1-methylimidazole were added into a 2000 ml three-neck round-bottom flask. The reaction temperature was set from 75 to 80° C. After four hours, the milk-like solution transferred into homogenous solution. The reaction was continued for three days. Then, the product was washed with ethyl acetate five times. After that, it was dried in vacuum for three days.
