1,4-Cyclohexanedione - Preparation Method

Open Data Verified Data

add the prepared sodium ethoxide to the reaction kettle, add diethyl ether and diethyl succinate, dissolve in water and reflux for 3 days, recover the diethyl ether; Then cool to room temperature, add 10% dilute sulfuric acid to adjust to pH = 2, the crystals were filtered off, washed with water, and dried to give crude diethyl succinate; The crude product was recrystallized from ethanol (melting point 127-129 ° C.) to give a pure product. Then add diethyl succinate back to the flask, add the mixture of concentrated sulfuric acid, water and ethanol, refluxed in oil for 5 days, cool, neutralize with ammonia water to pH = 8, and then extract 4 times with chloroform, the crude product is obtained by recovering chloroform; The crude product is then subjected to vacuum distillation, and the distillate is poured into cold petroleum ether, filtered and dried, I .e., 1,4-cyclohexanedione product.
