HCID 442197041-Benzyl-3-hexadecyl-2-methylimidazolium chloride

Procedure

The procedure of Example 1 was repeated with minor change. 427 g of 1-chlorohexadecane (Aldrich) and 280 g of 1-benzyl-2-methyl imidazole (Shikoku Chemicals Corp. 1B2MZ) 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 a homogenous solution. The reaction was continued for four days. Then, the product was washed with ethyl acetate five times. After that, it was dried under vacuum for three days.
