1,5-Dibromopentane(Cas 111-24-0) Usage
|
Preparation |
1,5-Dibromopentane was obtained by ring-opening bromination of tetrahydropyran. In a 500ml flask, add 250g of 48% hydrobromic acid, 75g of concentrated sulfuric acid, 21.5g of redistilled tetrahydropyran (86.5-87.5°C fraction) in turn to a reflux condenser and heat the brown mixture gently to reflux for 3h. After cooling to room temperature, partition the lower layer of dibromide and wash each with saturated sodium carbonate solution and water once. Dried with anhydrous calcium chloride. Distill under reduced pressure and collect the 104-106°C (2.53 kPa) fraction as 1,5-dibromopentane in 46-47 g yield and 80-82% yield.1,5-Dibromopentane synthesis route |
