| titleOfInvention | Processes for production and purification of normal propyl bromide |
| abstract | A process for oxygen-initiated hydrobromination of propene to form a crude reaction mixture of 95 GC area % n-propyl bromide. The process includes feeding an oxygen-containing gas, propene and hydrogen bromide into a liquid phase mixture comprised of n-propyl bromide and hydrogen bromide. At least the oxygen-containing gas and the propene of the feed are fed subsurface to the liquid phase mixture and either (a) the oxygen-containing gas and the propene do not come together in the absence of hydrogen bromide or (b) the oxygen-containing gas and the propene come together only in a propene:oxygen molar ratio in the range of 145:1 to 180:1. Purification processes provide a propyl bromide product containing at least 99.7 GC area % n-propyl bromide. Also provided is a novel composition of enhanced thermal stability which comprises a mixture of n-propyl bromide and isopropyl bromide. The mixture has an n-propyl bromide content of at least 99.7 GC area %, and an isopropyl bromide content of no more than 0.05 GC area %. The mixture, if subjected to storage in a closed chemically inert container at 60°C for at least 480 hours, has an APHA color of 10 or less while the mixture is devoid of any added stabilizer component. |
