Application of 41253-21-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 41253-21-8 name is Sodium 1,2,4-triazol-1-ide, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
At room temperature, 113g of acetonitrile was added to the four-necked flask.1,2,4-triazole sodium salt (18.20 g, 0.2 mol),2,4′-Dichloroacetophenone (37.80 g, 0.2 mol), heated to 80-85 C,The reaction was 1-2 h, the reaction was completed, the solvent was evaporated to dryness under reduced pressure, 50 g of water was added, and extracted with 150 g of dichloromethane, and washed with water.The solvent was dried to give a white solid with a qualitative content of 98%.The weight yield was 96%.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Sodium 1,2,4-triazol-1-ide, and friends who are interested can also refer to it.
