In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 41253-21-8 as follows. COA of Formula: C2H2N3Na
a stirrer after replacement with nitrogen,Add the thermometer and condenser to the reaction bottle1-(4-chlorophenyl)-4,4-dimethyl-3-butanone100g,Trimethyl thionyl chloride 63g,28 g of potassium hydroxide and 100 g of dimethyl sulfoxide (DMSO) and stirred.After 40 C reaction to 1 – (4 – chlorophenyl) – 4,4 – dimethyl -3 – pentanone reaction,Add sodium triazole sodium 60g, react at 120 C,After the reaction, desolvation, add 100 g of methylcyclohexane, and wash with 30 g of water.Layering at 70 C, recrystallization from water at 25 C,After suction filtration, the mixture was dried to obtain 130 g of tebuconazole, the yield was 91%, and the purity was 96%.
According to the analysis of related databases, 41253-21-8, the application of this compound in the production field has become more and more popular.
