  Phthalate Plasticizers Covalently Bound to PVC: Plasticization with Suppressed Migration

  摘要：

  The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a good plasticization efficiency is achieved although flexibility is reduced compared with that of commercial PVC-phthalate systems. However, the migration is completely suppressed. This approach may open new ways to the preparation of flexible PVC with permanent plasticizer effect and zero migration.

  the substrate and catalyst at room temperature. Its potential applications to organic transformations are demonstrated by the synthesis of various biologically active N-heterocycles such as indoles, (iso)quinolines and β-carbolines and natural products such as eudistomin U, norharmane, and harmane and precursors to perlolyrine and flazin. Without isolation and purification, the catalyst solution can

  本文中，描述了一种在双相介质中使用可重复使用的均相钴-酞菁光氧化还原催化剂对四氢-β-咔啉，二氢吲哚和四氢-（异）喹啉进行氧化脱氢（ODH）的简单有效的方法。双相系统具有易于分离产物和均相光氧化还原催化剂有效重复使用的优点。而且，当前系统显着帮助克服了室温下底物和催化剂的溶解性问题。通过合成各种具有生物活性的N-杂环（如吲哚，（异）喹啉和β-咔啉）以及天然产物（如eudistomin U，降伤害药烷和harmane）以及全氟去氧灵和flazin的前体，证明了其在有机转化中的潜在应用。没有分离和纯化，催化剂溶液最多可重复使用5次，反应活性几乎相当。此外，以克为单位证明了反应的效率。据我们所知，这是有关在环境友好的条件下使用非贵重，可重复使用和均相的钴光氧化还原催化剂进行ODH反应的第一份报告。

  Gas resistance of an image is evaluated by placing the image in a mixed gas atmosphere containing at least ozone and nitrogen dioxide. The mixed gas atmosphere is controlled such that the concentrations of ozone and nitrogen dioxide are not less than 75 ppb and not less than 150 ppb, respectively, and the mixed gas is continuously supplied to the surface of a sample bearing the image at a flow rate not less than 0.2 m/s and not more than 3.0 m/s.

  Treatment of the manganese(II) chelate of tetra- sodium 3,10,17,24-tetrasulphonatophthalocyanine (tspc) with alkaline aqueous solution in air followed by the addition of ethanol leads to formation and precipitation of an ESR non-detectable form of the chelate. When the material is dissolved in slightly alkaline aqueous solution and allowed to stand under nitrogen or air for two hours, a product is
