    • The invention relates to polymeric organosiloxane ammonium salts having a silica-like skeleton and including units of Formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and signify a group of Formula (II): ##STR2## wherein R.sup.5 is an alkylene group and the oxygen atoms are saturated by silicon atoms of additional groups corresponding to Formula (II), optionally with the insertion of cross-linking agents; R.sup.3 represents groups corresponding to R.sup.1 or R.sup.2, or hydrogen or an alkyl group; R.sup.4 represents hydrogen or an alkyl group; x is the charge number of an oxo anion of a monooxo-, isopolyoxo- or heteropolyoxo acid of the elements vanadium, niobium, tantalum, molybdenum or tungsten; and oxo groups of the X anion also may be replaced by peroxo groups. The invention also includes methods of preparing the salts of Formula (I) from salts of the type (R.sup.1 R.sup.2 R.sup.3 R.sup.4 N.sup.+).sub.y Y wherein Y is different from X. The invention further includes the use of the salts of Formula (I) as catalyst for oxidation reactions using peroxo compounds as an oxidation agent.

    • An aqueous hydrogen peroxide extract which contains small amounts of dispersed working solution and a working solution which contains small amounts of dispersed aqueous hydrogen peroxide are collected in the extraction stage of the anthraquinone method for preparing hydrogen peroxide. In order to purify these solutions, the working solution is compounded with aqueous hydrogen peroxide or preferably with water and the hydrogen peroxide extract is compounded with an organic dissolving mixture, preferably a quinone dissolver, and the respective dispersed phase is separated out with the aid of coalescers in a separator unit. It is especially preferable to add 1-3% by volume water or 1-3% quinone dissolver before the coalescer stages and to use coalescers with a drop-enlarging design and filter layers consisting of thermally desized glass filament yarn.The after-purification in accordance with the method results in a hydrogen peroxide which is improved as regards carbon content and color index as well as in an increase in yield of hydrogen peroxide and in a working solution with constant rel. moisture.
    • 在用于制备过氧化氢的蒽醌方法的萃取阶段中收集含有少量分散的工作溶液和含有少量分散的过氧化氢水的工作溶液的过氧化氢水提取物。 为了纯化这些溶液,将工作溶液与过氧化氢水溶液或优选与水混合,并将过氧化氢提取物与有机溶解混合物(优选醌溶解器)混合,并将相应的分散相借助于 分离器单元中的聚结器。 特别优选在聚结器阶段之前加入1-3体积%水或1-3%醌溶解剂,并使用滴加扩大设计的聚结器和由热退浆玻璃丝线组成的过滤层。 根据该方法的后净化产生了关于碳含量和颜色指数以及过氧化氢产率的增加和具有恒定相关性的工作溶液中改善的过氧化氢。 湿气。
