| Production method | The hexadiol was brominated: in 500ml flask with reflux condenser, 58g 1-hexanediol and 6.84g red phosphorus were added into the flask and heated to 100 ℃. After adding 80g bromine, the reactants were cooled to room temperature and diluted with water. After adding 80g bromine, excessive red phosphorus was filtered out and the dibromate ether solution was separated. The product was washed with 10% sodium sulfate solution and water in turn, dried with anhydrous calcium chloride, then distilled by vacuum distillation, collected at 114 ℃, 115 ℃ and 1. 6kpa. the finished product was obtained by 85 g. The yield is 71%. |
