2,3-二溴丙基 乙酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a 500-ml flask, 65 g of 2,3-dibromopropyl acetate (0.25 mole), 10 ml of water, 100 ml of methanol and 44 g of 50 percent sodium hydroxide (0.55 mole) are mixed giving an exothermic reaction. The mixture is then stirred at 60° C.-65° C. for 5 hours and allowed to cool. To this mixture is added 200 ml of water but no phasing occurs. The water phase is extracted twice with 150-ml portions of methylene chloride and these layers dried over sodium sulfate, filtered and distilled to give a 100 percent conversion of the 2,3-dibromopropyl acetate with a 38 percent yield of epibromohydrin. giving an exothermic reaction to cool The water phase is extracted twice with 150-ml portions of methylene chloride these layers dried over sodium sulfate filtered distilled
