Abstract: 1465756 Phthalamide BASF AG 9 July 1974 [10 July 1973] 30292/74 Heading C2C A continuous process for the preparation of phthalimide comprises reacting phthalic anhydride with ammonia at elevated temperature, washing the off-gas with a melt which contains at least 70% by weight of phthalimide, at a temperature of not less than 210‹ C., and feeding the melt to the reaction. Preferably the reaction is carried out in countercurrent and the wash column is combined with the reactor by using a tray column, the phthalic anhydride melt being fed continuously to one of the middle trays, the ammonia being introduced at the bottom of the column, and the phthalimide melt, as the wash fluid, being introduced at the top of the column.
