반응 단계
The cyclobutane-1,2,3,4-tetracarboxylic acid (501 g, 2.16 mol) and acetic anhydride (3000 ml) were added to a 5-liter flask and reacted at a controlled temperature of 150° C. for 24 hours. The reaction was cooled to room temperature; concentrated; and dried to obtain 1,2,3,4-cyclobutanetetracarboxylic dianhydride (573 g, 2.93 mol).
