摘要:越简单越好.设计并合成了一系列简单,中性和超低分子量(mw:140-200)的酰肼类超分子凝胶剂,并通过两个简单的步骤进行了合成.对于非共轭的衍生自环己烷的酰肼,它们的单体可以通过分子间氢键和偶极-偶极相互作用自组装形成凝胶.重要的是,共轭邻苯二甲酰肼可以通过分子间氢键自聚集成平面和圆形三聚体,然后通过分子间π-π堆积相互作用自组装形成凝胶.有趣的是,这些简单的胶凝剂表现出不同寻常的特性,例如自我修复,多响应荧光以及手性(R)/(S)-1,1'-联萘-2,2'-二胺和s 2−分别通过不同的凝胶重整时间和蓝绿色变色时间.这些结果强调了超分子凝胶的重要性,并扩展了超分子胶凝剂的范围.

权利人:EURENCO FRANCE
摘要:The present invention relates to a sequential one-pot synthesis of TKX-50, suitable for larger-scale production, during which an acetyl halide is used during the cyclization of diazidoglyoxime so as to obtain 1,1′-diacetyl-5,5′-bistetrazole, which is then hydrolyzed to 5,5′-bistetrazole-1,1′-diolate, to which compound a hydroxylammonium salt is subsequently added.

标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
