HCID 27342231-Methyl-3-octylimidazolium chloride

Procedure

The procedure of Example 1 was repeated with minor changes. 654 g of 1-chlorooctane and 360 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. After two days, 60 g of 1-chlorooctane was added into the reactor. The reaction was continued for three days. Then, the product was washed with ethyl acetate five times and toluene three times. After that, it was dried in vacuum for three days.
