标题:六氯碘酸盐(iv)对苯酚的过度氧化
摘要:先前已经确定,由于[ircl 6] 2-的缺乏,苯酚的水氧化过程通过[ircl 6] 3-和苯氧基的产生而进行.苯氧基自由基的偶联主要产生4,4'-联苯酚,2,2'-联苯酚,2,4'-联苯酚和4-苯氧基苯酚.这些偶联产物的进一步氧化会导致过氧化,从而导致最终产物的混合物非常复杂.[ircl 6] 2-对四种偶联产物的氧化速率定律与苯酚本身的氧化速率定律具有相同的形式:-D [ir Iv] / D T = {(k Aroh + Karo-K A / [h +])/(1 + K A / [h +])} [aroh] Tot [ir Iv].已在25oc下确定了四种底物的k Aroh和k Aro-值,并将其分配给h 2O-Pcet和电子转移机制分别.包括苯酚的氧化速率以及这些过氧化步骤的速率在内的组合机理的动力学模拟表明,过氧化的程度在高ph值下相当有限,而在低ph值下则相当

摘要:The present invention provides new properties by adding boron nitride nanosheet (BNNS) (13) as well as chemically synthesizing the VOC adsorbent. Poly(2,6-diphenyl-p-phenylene oxide) (PPPO), known under the trademark of Tenax, was produced as a polymeric adsorbent by reinforcing with BNNS in granule form and high capacity, and it was called as MPPPO-BN adsorbent (21). The use of MPPPO-BN adsorbent (21) as an adsorbent material for VOCs has been proven by desorption tests from ambient temperature to 340°C depending on VOCs.The product developed with BNNS additive, being used as a polymeric adsorbent, has the capacity to adsorb more VOCs, prevent the agglomeration of polymer particles, and have a higher density than Tenax TA and Tenax GR.

标 题 :Polymer bound multidentate complexes
发明人：GAUL JR JOHN H; DRAGO RUSSELL S
权利人:UNIV ILLINOIS
摘要:Polymer bound multidentate complexes are prepared by reacting pendant benzyl chloride and benzyl iodide groups on a variety of polymer supports, including crosslinked polystyrene, with 3,3'-iminodiproprionitrile and reducing the nitrile groups by treatment with, for example, a boron hydride-tetrahydrofuran complex to form the amine. The amine is a precursor for other ligand systems; for example, the primary amine groups formed condense with an aldehyde or ketone to yield five coordinate Schiff base ligands. The polydentate amine ligand systems are useful for synthesis of chelating agents for sequestering metal ions from solution for purification or concentration purposes. Metal complexes of these ligands with manganese, iron, cobalt, nickel, copper, and zinc can be prepared which are useful as heterogeneous oxidation catalysts.
