2,3-Dibromopropene Use and Manufacturing

Methods of Manufacturing

Heat 1, 2, 3-tribromopropane and solid sodium hydroxide to boil, and the product is distilled. The distillate contains 2, 3-dibromopropene and unreacted 1, 2, 3-tribromopropane, which is washed with water Perform vacuum distillation, collect the 95°C (10kPa) front fraction and re-fractionate, and collect the 73-76°C (10kPa) fraction to obtain 2, 3-dibromopropene with a yield of 74-84%.

Uses

Organic synthesis intermediate.
