1. A method for preparing an ionic liquid comprising:
- (1) reacting a heteroatomic compound with dialkylcarbonate to produce an alkylcarbonate salt of the heteroatomic compound;
(2) acidifying the alkylcarbonate salt with a sulfate-containing acid to produce a bisulfate salt of the heteroatomic compound; and
(3) converting the bisulfate salt of the heteroatomic compound to an ionic liquid comprising an alkyl-heteroatomic cation and an anion.
