实验步骤: 1.15 g(0.05 moles) of sodium in small pieces are added under a nitrogen atmosphere to 43 g (0.50 moles) of absolute cyclopentanol, and the mixture is stirred at 60° until all the sodium is dissolved after a period of 16 hours. After the solution has been cooled to 20°, 11.5 g (0.05 moles) of 1,5-dibromopentane are added and the mixture is stirred under reflux for 18 hours. The precipitated sodium bromide is then removed by filtration and the filtrate is freed of excess cyclopentanol by distillation. The fraction boiling in the temperature range 115°-118°/1.0 mm is collected, and consists of the desired product. is dissolved after a period of 16 hours After the solution has been cooled to 20° under reflux for 18 hours The precipitated sodium bromide is then removed by filtration the filtrate is freed of excess cyclopentanol by distillation range 115°-118° is collected
