Procedure

German Published Application DAS No. 1,191,652 discloses that, for example, pyridinium ethylsulfate (2-pyridinium-1-sulfatoethane) can be prepared in an expensive manner by reacting hydroxyethylpyridinium chloride, obtained from pyridine and ethylene chlorohydrin, with chlorosulfonic acid. In this procedure too, the yield and purity are unsatisfactory.
