Chemische Eigenschaften

white to off-white powder

Verwenden

Imidazolium modified PPO with liquid ionic graphene oxide can be used as an anion exchange membrane (AEM) composite with a peak power density of 136 mW cm?2 for use in the fabrication of high performance fuel cells. It may also be sulfonated to form a long chained polymeric structure with an efficiency of 81.8% at a current density of 120 mA cm?2 for potentiall use in vanadium redox flow batteries (VRFBs) as effective energy storage systems. It may also be used in the formation of AEMs, which can be used in the development of microbial desalination cell system (MDCS).

synthetische

Oxidative coupling is readily accomplished by passing oxygen into a reaction mixture containing 2,6-xylenol, pyridine and cuprous chloride. (The molar ratio of pyridine to cuprous ion is generally in the range 10: 1 to 100: 1.) External heating is unnecessary; during the course of the reaction the temperature rises to about 70??C. The polymer is precipitated with dilute hydrochloric acid and collected by filtration.
It is generally accepted that aryloxy radicals are intermediates in the polymerization reaction since ESR studies have shown the presence of both monomeric and polymeric aryloxy radicals in polymerizing solutions of 2,6- xylenol. The simplest mechanism that can be suggested for the reaction is aromatic substitution:
