    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: In producing aqueous microbiocidal solutions by oxidation of a water-soluble alkali metal bromide, an intolerable loss of active halogen species has been found to occur during a 10-day period immediately after the product solution has been formed. Surprisingly, this loss has been found to result from an alcohol impurity in the alkali metal bromide used in the process. By eliminating or at least sharply reducing the amount of alcohol impurity in the reaction mixture, products are formed which do not undergo the intolerable loss of active halogen content during the 10-day period.

    摘要: Bisphenol-A-bis(neopentylglycolphosphate) products of enhanced properties and processes for preparing them are described. One of the processes includes (a) mixing and reacting neopentyl glycol and bisphenol-A-bis(dichlorophosphate) in an inert polar organic solvent which (1) if mixed by itself with an equal volume of water at 25° C., will form a separate phase, (2) the solvent by itself will dissolve at least about 10 wt % of bisphenol-A-bis(neopentylglycolphosphate) at a temperature in the range of 25 to 50° C., and optionally but preferably (3) the solvent by itself can be completely vaporized at a temperature below about 180° C.; (b) washing bisphenol-A-bis(neopentylglycolphosphate) product formed in a) while dissolved in inert organic solvent having such characteristics at least once with an aqueous alkaline washing solution; and (c) optionally but preferably, recovering bisphenol-A-bis(neopentylglycolphosphate) product from organic solvent having such characteristics. The reaction of (a) can be conducted in an inert non-polar solvent if that solvent is replaced by an inert polar organic solvent satisfying (1) and (2), and preferably (3). A solvent satisfying (1), (2), and (3) is used when (c) is conducted by distilling or vaporizing off the solvent to recover the bisphenol-A-bis(neopentylglycolphosphate) product as such. The product has a low acid number or a high thermal stability, and usually both.
