YieldReaction ConditionsOperation in experiment
82.8% With sulfuric acid; acetic acid In 5,5-dimethyl-1,3-cyclohexadiene at 130℃; for 5.00 h; In a 100 mL three-necked flask equipped with a thermometer, a magnetic stirrer, a water separator, and a condenser tube was added 9.64 g of hydrogenatedEthylbenzene tetracarboxylate, 1mL of concentrated sulfuric acid, 5mL of acetic acid and 50mL of xylene were heated to 130°C. During the reaction, the reaction temperature was maintained at reflux, and the reaction continuously removed water for 5 hours. , cooling down to room temperature, suction filtration, filter cake washed with acetone, dried at room temperature under reduced pressure to give white solid 1,2,4,5-cyclohexane tetracarboxylic acid anhydride 4.80g, yield: 82.8percent.

YieldReaction ConditionsOperation in experiment
97.5% for 1.00 h; Inert atmosphere; Reflux 39.2 g of hydrogenated pyromellitic acid (0.15 mol) having a purity of 99.50percent obtained in the step 1 was added to 500 mL four-necked flask , meanwhile adding 120 g of acetic anhydride (1.18 mol) and heating to reflux under a nitrogen atmosphere ,to carry out Dehydration reaction for 1h. [0026] After the reaction was completed, the solution was cooled to precipitate white crystals and filtered. The filter cake was dried under reduced pressure to obtain 32.5 g of white solid hydrogenated pyromellitic dianhydride. The yield was 97.5percent and the purity of GC was 99.85percent.
80% for 1.00 h; Inert atmosphere; Reflux In a three-necked flask equipped with a thermometer, mechanical stirring, and reflux condenser, 100 g of hydrogenated pyromellitic acid and 800 g of acetic anhydride was refluxed for 1 h under protection of nitrogen. Cool to room temperature to precipitate crystals and separate the crystals.Using 50 g of acetic anhydride and drying, 68.9 g of 1,2,4,5-cyclohexanetetracarboxylic dianhydride was obtained. Yield: 80percent.
