| HPMDA Usage And Synthesis |
| Uses | 1,2,4,5-Cyclohexanetetracarboxylic dianhydride can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development and chemical and pharmaceutical production processes. | | Synthesis | 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: 82.8%. |
