    • This invention provides oligomeric hydrogen phosphonates represented by the formula (I) where R is an alkyl group having one to about six carbon atoms; R' is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group having two to about twenty carbon atoms or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring, where at least one of R' is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group and at least one of R' is a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; and n is a number from 2 to about 20. Also provided are processes for making these oligomeric hydrogen phosphonates, oligomeric organophosphonate compositions, and processes for making these oligomeric organophosphonate compositions.

    • A process for producing reaction-derived decabromodiphenylalkane product, especially decabromodiphenylethane product, of high assay is described. Diphenylalkane, preferably diphenylethane, is brominated by introducing the selected diphenylalkane in the form of a mist or spray into a reaction zone containing a reaction mixture having a liquid phase comprised of excess bromine and Lewis acid bromination catalyst, so that mist or spray of diphenylalkane descends onto and contacts the liquid phase of the reaction mixture and bromination of the diphenylalkane occurs to produce reaction-derived decabromodiphenylalkane product of high assay. Preferably, the reaction mixture is maintained under reflux and optionally is also stirred.
    • 描述了高分离反应衍生的十溴二苯基烷烃产物,特别是十溴二苯乙烷产物的方法。 将二苯基烷烃,优选二苯基乙烷通过将选择的以雾或喷雾形式的二苯基烷烃引入含有由过量的溴和路易斯酸溴化催化剂组成的液相的反应混合物的反应区中进行溴化,使得二苯基烷烃的雾或喷雾下降 发生并接触反应混合物的液相并发生二苯基链烷烃的溴化,以产生高分析反应的十溴二苯基烷烃产物。 优选地,将反应混合物保持回流并任选地还搅拌。
