| production method | 1. Preparation Method: In the reaction bottle equipped with stirrer, reflux condenser (equipped with calcium chloride drying tube), dropping funnel, thermometer, add allyl bromide (2)182g(1.5mol), ML of dried carbon tetrachloride. The ice-salt bath was cooled to -5 ° C., and 255g(1.6mol) of dry bromine was added dropwise through a dropping funnel. The dropping acceleration was controlled so that the reaction solution rose to 0 ° C., and the addition was completed for about 1.5h. Slowly up to room temperature and continue to stir the reaction for 30min. The solvent was distilled under reduced pressure, and then a fraction of 92 to 93 ° C./1.33KPA was collected to obtain 400g of 1,2, 3-tribromopropane (1) as an almost colorless liquid in a yield of 95%. Note: (1) The allyl bromide is preferably treated before use, and the treatment method is as follows: first, dry with anhydrous calcium chloride, and then carry out distillation, and collect the fraction of 69~72 °c.
