ABSTRACT:
Water is removed from methanesulfonic acid to produce an anhydrous product of high purity by spraying wet methanesulfonic acid (MSA) onto the walls of a vertical, heated tube which is maintained at reduced pressure. The water evaporates as the acid flows down the walls of the tube and dry MSA is removed at the bottom.
