Abstract

The invention relates to a process for the prepn. of ionic liqs. of general formula (cation)(R'-O-SO3). The process includes the step of treating the compd. of formula (cation)(R-O-SO3) with an alc., or mixt. of different alcs., of the formula R'-OH optionally in the presence of a catalyst to form the desired ionic liq. and the byproduct R-OH, which is optionally removed during the reaction or after completion of the reaction. The compd. of formula (cation)(R-O-SO3) can be prepd. by alkylating a tertiary or arom. amine with a dialkylsulfate. [on SciFinder(R)]
