    摘要： 1-Bromopropane is produced from hydrogen bromide, propene and a catalytically effective amount of an ozonide catalyst and/or one or more active catalytic species formed in situ therefrom. In addition to being highly efficient and highly suitable for use on an industrial scale, the process has the additional advantages of being environmentally friendly, operationally safe, and conservationally beneficial.

    摘要： A new, highly selective way of removing bromine contamination from a gaseous stream comprised of hydrogen bromide and bromine is described. Such process technology involves non-catalyzed free radical (benzylic) bromination of an alkylene-bridged aromatic hydrocarbon and/or certain alkyl-substituted aromatic hydrocarbons and recovering the purified gaseous HBr. Because of the high selectivity of the bromination on the aliphatic bridges or side-chains, virtually no ring bromination occurs, and this enables recovery of the bromine values in the form of HBr. Thus preferably, the bromine is recovered as HBr from the scrubbing liquid by subjecting the scrubbing liquid to thermal or catalytic dehyrobromination. In plant operations, the gaseous HBr purified in the process can then be introduced into a compressor to produce either liquid or gaseous HBr for storage under pressure. Alternatively, the purified gaseous HBr can be fed directly into one or more reactions in which HBr is used as a reactant.

    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： Emulsion formation is minimized or prevented and hydrolytic product degradation is suppressed during purification of impure bisphenol-A bis(diphenylphosphate). This is accomplished by forming a hydrocarbon solution of bisphenol-A bis(diphenylphosphate) plus impurities in a solvent comprising at least one aromatic hydrocarbon and at least one paraffinic hydrocarbon. Optionally, but preferably, this solution is washed with water or an aqueous buffer solution. Next, the hydrocarbon solution is washed one or more times with an aqueous alkaline washing solution that has a specific gravity that differs from the specific gravity of the hydrocarbon solution by at least about 0.05 gram per cubic centimeter. After each washing the mixture settles into a purified organic phase and a separate aqueous phase, and these phases are separated from each other. After completing the one or more alkaline washings and separations, the resultant purified organic phase is washed one or more times with water to remove alkaline components from the hydrocarbon solution, and after each such washing the washed mixture is settled into a less alkaline purified organic phase and a separate aqueous phase. These phases are separated, and preferably the purified product is recovered from the organic phase.
