摘要:
A method for electrocatalytically reacting various oxidizable organic compounds by introducing current by means of an anode into an electrolyte of a cell containing the oxidizable organic compound. The anode comprises an electrocatalyst material which has at least one compound of the formula: wherein A is selected from any of the pyrochlore structure metal cations of: Pb, Bi and TI, wherein B' is selected from any of the pyrochlore structure metal cations of Pb, Bi TI and Sn; wherein B is a pyrochlore structure metal cation, at least a major portion of which is selected from at least one of: Ru, Rh, Ir and Os, wherein y is equal to or greater than zero and equal to or less than one; and wherein x is equal to or less than one and equal to or greater than zero.

Stickstoffhaltige Verbindungen enthaltende Polycarbonsäuren, die durch Oxidation cyclischer Alkene mit Salpetersäure erhalten wurden, reinigt man erfindungsgemäß durch oxidative Nachbehandlung. Besonders geeignete Oxidationsmittel für diese Nachbehandlung sind Salpetersäure oder Wasserstoffperoxid. Anschließend an den Reinigungsschritt werden die Polycarbonsäuren insbesondere mit Wasser oder mit C 2 - bis C 8 -Carbonsäuren gewaschen.
摘要:
The present invention relates to a plasticizer composition, a resin composition, and methods for preparing the same. The present invention can provide: a plasticizer composition capable of improving physical properties required for a plasticizer composition contained in a vinyl chloride-based resin composition, such as plasticizing efficiency, weight loss on heating, and migration resistance, to equivalent or higher levels compared with existing plasticizer compositions, and a resin composition comprising the same.
摘要:
Compositions for reducing the aggregate content of a protein preparation include a first substrate having a first surface-bound ligand possessing a metal affinity functionality and a second surface-bound ligand optionally provided on a second substrate and having an aggregate charge opposite to that of the metal affinity functionality of the first substrate, wherein the first surface-bound ligand and the second surface-bound ligand are positioned such that the protein preparation may contact both the first surface-bound ligand and the second surface-bound ligand simultaneously.
