실험 절차
To a 30 mm co-rotating twin screw extruder (Werner & Pfleiderer ZSK type) was added at barrel 1 (of 14) 2370 g (16 mol) per hour phthalic anhydride in the form of crushed pellets, and at barrel 2 molten 1-naphthylamine at a rate of 2234 g (15.62 mol) per hour while maintaining a temperature profile of: zone 1=75°, zone 2=83°, zone 3=95°, zone 4= 75° and zone 5=45° C. At a screw speed of 300 rpm, the residence time was about 60 seconds, resulting in a product containing N-1-naphthylphthalamic acid (4365 g, ca. 96% yield based on 1-naphthylamine).
