실험 절차
3,4,6-Trichlorophthalic acid (500 g, 1.86 moles), glacial acetic acid (4 L), and aniline (175 mL, 1.92 moles) were charged to a 12 L 3-neck flask equipped with a condenser, a stirrer and a thermometer. The mixture was heated with stirring and maintained at 100°-101° C. for 2 hours, then cooled to room temperature and filtered. The filter cake was washed with cold water and vacuum dried (70° C., 0.2 mmHg) for 24 hours to yield 590.7 g of 97.5% pure 3,4,6-trichloro-N-phenylphthalimide (m.p. 199°-200° C.).
