    摘要: 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.

    摘要: Processes are provided for conjointly producing Br2 and a concentrated aqueous solution containing at least about 5 wt % CaCI2, based on the weight of the concentrated aqueous solution, from an aqueous HBr rich stream and, optionally, a feed brine dilute in CaCI2. Such processes can comprise feeding the aqueous HBr-rich stream and the feed brine to a tower, oxidizing bromide moieties within the tower with Cl2 to produce Br2, recovering Br2 from the tower, removing a bromide-depleted bottoms from the tower, such bottoms containing HCI, adding a Ca++ source to the bromide-depleted bottoms to convert substantially all of the HCI in the bottoms to CaCI2, and, as necessary, removing water from the treated bottoms to produce the concentrated aqueous solution.
