Preparation of 1-Bromobutane:
Place 30 cm³ of water, 35 g of powdered sodium bromide and 25 cm³ of butan-1-ol in a 250 cm³ round bottomed flask. Fit a tap funnel to the flask via a stillhead. Place 25 cm³ of concentrated sulphuric acid in the tap funnel, and then allow the acid to fall drop by drop into the flask, keeping the contents well shaken and cooled occasionally in an ice-water bath. When the addition is complete, replace the tap funnel and stillhead with a reflux water condenser and gently boil the mixture over a sand-bath for about 45 minutes, shaking the flask gently from time to time.Remove the reflux condenser and rearrange the apparatus for distillation. Distil off the crude 1-bromobutane (about 30 cm³). Shake the distillate with water in a separating funnel, and run off the lower layer of 1-bromobutane; reject the aqueous layer.Return the 1-bromobutane to the funnel, add about half its volume of concentrated hydrochloric acid, and shake. Run off and discard the lower layer of acid. Shake the 1-bromobutane cautiously with dilute sodium carbonate solution, cautiously releasing the pressure at intervals.Run off the lower layer of 1-bromobutane and add some granular anhydrous calcium chloride. Swirl the mixture until the liquid is clear. Filter the 1-bromobutane into a clean dry flask, and distil it, collecting the fraction boiling between 99 - 102°C.

Safety Information of 1-Bromobutane:
The 1-Bromobutane is irritating to eyes, respiratory system and skin and toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.This material and/or its container must be disposed of as hazardous waste.
