Reaktionsschritte

U.S. Pat. No. 3,812,130 describes reacting solid 1,8-naphthalic anhydride with gaseous ammonia to produce 1,8 naphthalimide. The product is isolated directly by evaporating off the water. Although this procedure minimizes waste water, it still requires a pressure vessel and has the disadvantage of not allowing for any water soluble impurities or unreacted starting material to be removed after the reaction. Thus, a potentially impure product is produced.
