2-Furancarboxylic acid, hydrazide Use and Manufacturing
Furan-2- carboxamide 111.1g, 224g of acetone azine placed with stirring, Dropping funnel, Thermometer and distillation column in a four-necked flask, The upper part of the receiver of the distillation column is connected with a conduit to absorb ammonia gas;Open the stir, The solution was heated to a temperature of 100 to 120 ° C, Carboxamide be 2-furyl all dissolved in acetone azine, 70 ml of water was slowly added dropwise to a four-necked flask, Control reaction temperature of 100 ~ 120 , When the gas produced by the reaction enters the rectification column, In the column temperature 54 ~ 58 under the acetone and recovery of ammonia, Water vapor condensed back to the flask to continue to participate in the reaction;After the water dripping continues to heat the reaction, The contents of 2-furancarboxamide in the reaction solution were analyzed, After the reaction of 2-furancarboxamide in the reaction solution was completed, The flask was connected to nitrogen and water in acetone with full vacuum distilled, The solid matter in the flask was recrystallized from ethanol, And dried to give 2-furoyl hydrazide 119.6g
