Soluble, fully cyclized m -amino phenyl acetylene terminated polyimides based on several anhydride/diamine monomers were prepared in N -methylpyrrolidine (... M Koná?,TM Moy,ME Rogers,... - 《Journal of Polymer Science Part B Polymer Physics》 被引量: 109发表: 1995年 The distribution of hy...
Silver oxalate and ammonium perrhenate (Ag : Re mol ratio of 1 : 1) were dissolved in a MilliQ®/ethylene diamine solution (4 : 1 mol ratio). Dried α-alumina powder was impregnated with this solution, up to 90% of its pore volume, aiming for a AgReO4 loading of ...
Carbon fibre based anion exchangers were prepared through electrochemical oxidation and bonding of ethylene diamine on fibre electrodes in acetonitrile and subsequent formation of the chloride salts of the ammonium groups.Catalytically active noble metals can be introduced into the carbon matrix after ion-...
Non-limiting examples of suitable amine compounds include: 1,2-diaminoethane; 1,3-diaminopropane; 1,4-diaminobutane; 1,6-diaminohexane; polyethylene amines such as diethylene triamine; triethylene tetramine; tetraethylene pentamine; polypropylene amines such as 1,2-propylene diamine; d-(1,2-propylen...
