    摘要: The invention relates to a novel process for preparing fluorosulfonic acid having low contents of low-boiling compounds in which hydrogen fluoride and sulfur trioxide are combined in stoichiometric amounts in a reaction vessel or by means of a reaction nozzle, the hot, gaseous fluorosulfonic acid that is formed is fed directly into a distillation column, and the fluorosulfonic acid is taken off at the bottom of the column or in the stripping section of the distillation column.
