Procedure: A 3-necked, 5-liter round-bottomed flask, equipped with a mechanical stirrer, was charged with 4,259 g (67.6 moles) of 99% nitric acid. To the flask was added 524.9 g (2.58 moles) N-butylphthalimide as a liquid at such a rate as to keep the reaction temperature under 40° C. The addition of the N-butylphthalimide was completed in about a half hour. The reaction was then heated for six hours to 50° C. in a temperature controlled water bath. The reaction product was then fed to a wiped film evaporator that was heated at 100° C. and under vacuum (30 mm). The bulk of the nitric acid was distilled off and the liquid product, i.e., 4-nitro-N-butylphthalimide and 3-nitro-N-butylphthalimide in a ratio of about 25:1, was isolated as a liquid which rapidly solidified to about 98% solids upon cooling in the collection vessel. Depending on the operation of the evaporator, the residual nitric acid in the product was less than 3% by weight, and was as low as 0.1% by weight. A 3-necked, 5-liter round-bottomed flask, equipped with a mechanical stirrer under 40° C was completed in about a half hour The reaction was then heated for six hours to 50° C. in a temperature The reaction product was then fed to a wiped film evaporator that The bulk of the nitric acid was distilled off

Procedure: A 10-gallon stainless steel reactor equipped with a turbine blade impeller, cooling coil, distilling condenser, azeotropic separator, thermocouple probe and means to maintain a nitrogen atmosphere, was charged with 15.335 kg (103.53 moles) phthalic anhydride. N-butylamine (7.663 kg, 104.57 moles) from a pressure vessel was slowly added to the reactor which was at room temperature, e.g., about 25° C. The resulting exothermic reaction between the amine and phthalic anhydride was continued until the temperature in the reactor rose to 90° C., at which time addition of amine was complete. The reaction mixture was then heated, with removal of water, for a 5 hour period until the temperature of the mixture reached 200° C. The reaction mixture then was maintained at 200° C. for 2 hours. The resulting product was vacuum distilled at a temperature ranging from 150°-155° C. and at a pressure of 20 mm, to afford a liquid which solidified. The melting point of the solid was about 34° to 35° C. and was produced at a 95% yield.
