    Abstract: Production of anhydrous 2-amino-1-methoxypropane (I) comprises (a) treating an aqueous reaction mixture (II) containing (I), obtained by reacting 1-methoxy-2-propanol with ammonia (NH3) on a catalyst, with aqueous sodium hydroxide (NaOH) solution to form an aqueous phase containing aqueous NaOH solution and a phase containing (I); (b) separating the phase (III) containing (I) from the aqueous phase; and (c) distilling (III) to separate an azeotrope of water and (I), which is recycled to step (a) or (b), and then anhydrous (I). Also claimed is a method of separating water from (II) in this way.
