Synthetic Route of 5343-92-0, 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. 5343-92-0, name is 1,2-Pentanediol, molecular formula is C5H12O2, The 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.
In a 1000 mL reaction flask, add 67 g of 1,2-pentanediol, 600 mL of toluene, 149 g of triethylamine, 40 g of calcium oxide, and 4.3 g of tetra-n-butylammonium hydrogen sulfate. Maintain the internal temperature at 0 to 5C, and slowly add the mixture under stirring. Sulfuryl fluoride gas 72g was reacted for 2 hours, nitrogen gas was blown for 1 hour, filtered, and the filtrate was desolvated under reduced pressure to obtain a solid crude product. Toluene 200 mL, 15-crown-5 0.05 g, 18-crown-60.05 g was heated and refluxed to dissolve. Slowly to room temperature, filtration, drying product 77g, yield 71.9%.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 5343-92-0, 1,2-Pentanediol.
