Adding a certain compound to certain chemical reactions, such as: 176969-34-9, name is 3-(Difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 176969-34-9, COA of Formula: C6H6F2N2O2<\/a><\/p>\n

To a one-necked flask was added 53.00 g 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid and 72 mL of thionyl chloride,Heating up to the system has a reflow phenomenon,After refluxing for 2 h, the unreacted thionyl chloride was evaporated at atmospheric pressure.System cooling to 60 below, an external anhydrous calcium chloride drying tower,Water pump vacuum distillation of low boiling impurities, get red viscous liquid, placed overnight solidified into white crystals.The yield was 78.25%.<\/p>\n
