Use | is used as a solvent for organic synthesis. |
production method | is obtained by the reaction of glycerol with red phosphorus and bromine. The glycerin and red phosphorus were mixed uniformly, and bromine was added dropwise under stirring, and the reaction was exothermic, and the temperature was about 80 °c. After the bromine was added, it was left overnight, and distilled under reduced pressure. The distillate was washed twice with 10% sea wave, dried with anhydrous sodium carbonate, filtered off the desiccant, and fractionated to collect 110-112 ℃(2.66kPa). The fraction is the finished product. |
