  直接巯基配体衍生的 UiO-66 用于去除含水汞及其随后作为转移乙烯基化催化剂的应用

  摘要：

  水中汞污染物的处理一直受到广泛关注。吸附是一种很有前途的除汞方法，已被广泛研究。然而，很少研究固定化汞的二次应用。本文研究了带有巯基的UiO-66对Hg的吸附行为。研究表明，UiO-66-SH的多孔结构和巯基可以有效促进水中汞的去除。此外，这项工作还推动了回收吸附剂的顺序应用，其中含有可能造成二次污染的吸附汞。回收的废吸附剂 UiO-66-S-Hg 成功地用作转移乙烯基化的有效催化剂，从而产生增值产品苯甲酸乙烯酯。已成功合成了八种乙烯基酯，收率高达 89%。该方法不仅为汞污染的治理，而且为二次污染的保护和固定化汞的资源化利用提供了一条有前景的途径。

  Production of vinyl halide-polyolefin graft copolymers by a liquid phase bulk polymerization process is carried out in the presence of a diluent. Suitable diluents preferably have vaporization pressure characteristics, within 6.89 x 102 kPa, and similar liquid state viscosity, as-vinyl-halide monomer. The diluents are soluble in vinyl halide monomer under the reaction conditions and are inert to the polymerization mass. The diluents are straight or branched chain or cyclic saturated hydrocarbons having from 3 to 15 carbon atoms. Particularly useful diluents are n-propane, n-butane, isobutane or mixtures thereof. The diluents are utilized in amounts from 0.2 to less than 50.0 percent based upon the total weight of the reaction charge. The polymers thus produced can be used to make moulded articles.

• Graft polymers of polymerizable monomers and olefin polymers

  公开号：EP0137519A2

  Graft polymers are prepared by reacting an ethylenically unsaturated polymerizable monomer with a polymer of an olefin of 2 to about 8 carbon atoms in a process wherein the olefin polymer is substantially insoluble in the monomer but is capable of absorbing the monomer. In a preferred aspect, a vinyl halide polyolefin graft polymer is produced by reacting a solid polyolefin particle with a vinyl halide monomer in which the polyolefin is substantially insoluble, but is capable of absorbing the monomer. The solid particles can be contacted with the monomer in one step or in stages. When the stage-wise reaction is continued until the proportion of polyolefin in the polymer product is about 2 to about 20 weight percent, the resulting product can be formed to a transparent or translucent article. When a small proportion of solid polyolefin is employed in the polymerization process, both a graft polymer and a polymer of the unsaturated monomer are simultaneously produced in the same reactor and can be readily mechanically separated into the individual products.

  接枝聚合物是通过乙烯基不饱和可聚合单体与 2 至 8 个碳原子的烯烃聚合物反应制备的，反应过程中烯烃聚合物基本上不溶于单体，但能吸收单体。在一个优选方面，卤化乙烯基聚烯烃接枝聚合物是通过固体聚烯烃颗粒与卤化乙烯基单体反应制得的，其中聚烯烃基本上不溶于卤化乙烯基单体，但能吸收单体。固体颗粒可以一步或分阶段与单体接触。当分阶段反应持续进行，直到聚合物产品中聚烯烃的比例达到约 2% 至约 20% 的重量百分比时，所得产品可形成透明或半透明制品。当在聚合过程中使用小比例的固体聚烯烃时，接枝聚合物和不饱和单体聚合物可在同一反应器中同时生产，并能很容易地机械分离成单个产品。
