Synthesis method

1. Obtained from the addition of propylene alcohol and bromine. Add propylene alcohol to the carbon tetrachloride solvent, perform bromination when adding bromine at 25-27°C, keep the temperature for 1 hour after adding (at 50±2°C), then distill to recover carbon tetrachloride, wash with water and sodium carbonate to pH The value is 7-8, dry, filter and clear, distill under reduced pressure, and collect the 140-160°C (2.66kPa) fraction as the finished product. It can also be produced without solvent: add propylene alcohol into the reaction pot, stir and cool. Add bromine dropwise below 10°C. The dropping speed is preferably such that the reaction temperature does not exceed 20°C. After the addition is completed, stir at room temperature for 1.5 hours, add water and stir for 10 minutes, let it stand, separate the oil layer, add sodium carbonate solution to neutralize it to neutrality. Leave to stand, separate the oil layer, distill under reduced pressure, and collect the 115-125°C (3.99-5.32kPa) fraction to obtain 2,3-dibromo-1-propanol.

2. Preparation method:

In a reaction bottle equipped with a stirrer, thermometer and dropping funnel, add 58g (1.0mol) of propylene alcohol (2) and 100mL of carbon tetrachloride. While cooling in a water bath, slowly add 160g of bromine dropwise. (1.0 mol), control the dropping speed to keep the temperature of the reaction solution at 25~27°C. After the addition is completed, slowly increase the temperature to 50°C and keep the reaction for 1 hour. Carbon tetrachloride was evaporated under reduced pressure, and the residue was washed with water and sodium carbonate solution until neutral. Dry with anhydrous sodium sulfate and distill under reduced pressure. Collect the fraction at 115~125℃/4~5.2kPa to obtain 175g of 2,3-1-propanol (1) with a yield of 80%. ^[1]
