  Ni / CeO 2催化剂对仲醇的自偶联

  摘要：

  研究了负载型镍催化剂在N 2气氛下无添加剂条件下脂族仲醇的液相C C自偶联。在各种Ni催化剂中，在H 2中预先还原的1或3 wt％Ni / CeO 2催化剂显示1-辛醇在130°C时自偶合的二聚产物（较高的酮）收率最高（94％）。 ，并且催化剂被重复使用。该催化剂对于各种仲醇的自偶联也是有效的，为温和条件下仲醇的自偶联提供了第一个非均相催化体系。研究了载体材料和Ni的氧化态对活性的影响，发现CeO 2金属镍对于该反应是必不可少的。提出了一种可能的反应机理，其中将由醇脱氢形成的酮进行醛醇缩合反应，生成α，β-不饱和酮，最后将其通过原位形成的Ni H物种进行氢化。

  Described is an insulating layer-forming composition, which contains a binder based on epoxy-thiol. The inventive composition, its rate of expansion ratio is relatively high, allows coatings having the layer thickness, required for the respective period of fire resistance, to be applied in a simple and fast manner, while at the same time the layer thickness is reduced to a minimum and yet a high insulating effect can be achieved. The composition of the invention is particularly suitable for fire protection, in particular as a coating of metallic and non-metallic substrates, such as steel components, like columns, beams, trusses, in order to increase the period of fire resistance.

  所描述的是一种绝缘层形成组合物，它含有一种基于环氧硫醇的粘合剂。本发明的组合物膨胀率相对较高，可以简单快速地涂抹出相应耐火期所需的涂层厚度，同时将涂层厚度降至最低，但仍能达到较高的绝缘效果。本发明的组合物尤其适用于防火保护，特别是作为金属和非金属基材的涂层，如钢制构件，如支柱、横梁、桁架等，以提高耐火期。

  A composition that forms an insulating layer is described, which contains a thiol-ene-based binder. With the composition according to the invention, the expansion rate of which is relatively high, coatings having the layer thickness necessary for the respective fire resistance time can be applied simply and quickly, the layer thickness being reduced to a minimum and a highly insulating effect still being achieved. The composition according to the invention is particularly suitable for fire protection, in particular as a coating of metallic and/or non-metallic substrates, for example steel components such as pillars, beams or truss members, to increase the fire resistance time.

  An insulating layer-forming composition, which contains an epoxy thiol-ene based binding agent is provided. The composition, the expansion rate of which is relatively high, enables coatings to be applied in the layer thickness required for the fire-resistance time concerned in a simple and rapid manner, wherein the layer thickness can be reduced to a minimum and a high insulating effect can still be achieved. The composition is especially suitable for fire protection control, more particularly as a coating of metallic and non-metallic substrates, for example steel components such as pillars, supports or frame members, for increasing the fire-resistance time.
