Research speed reading in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 41253-21-8, name is Sodium 1,2,4-triazol-1-ide belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 41253-21-8
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%.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 41253-21-8
