Product Name:Bromocyclopentane
CAS Number:137-43-9
Molecular formula:C5H9Br
Molecular Weight:149.03

Bromocyclopentane is synthesized by bromination of cyclopentanol: cyclopentanol is mixed with hydrobromic acid and heated to about 170°C refluxed for 6-8h. Then distilled with water steam, the oil layer is washed with 5% sodium carbonate, then dried, filtered, fractionated and collected 136-139°C fraction is the finished product. Another method is by the reaction of cyclopentanol and phosphorus tribromide: the cyclopentanol is cooled to 0 ℃, add the newly evaporated phosphorus tribromide drop by drop, add it all at 0-5 ℃, stir for 2h, and leave it at room temperature overnight. Add water and stratify, take the oil layer water distillation. Distillate stratification, the oil layer was washed with 10% sodium bicarbonate solution, dried with anhydrous calcium chloride, filtration, filtrate distillation, collect 134-141 ℃ fraction that is bromocyclopentane.
