2,6-二甲酚可以铜胺络合物为催化剂,在室温下与氧反应,生成聚2,6-二甲基1,4-苯撑氧(聚苯醚)。此聚合反应电可在阳极氧化下进行。同时放出等当量的氢。作者最近发现,酚类在适当电解条件下可以电氧化生成聚2,6-二取代基苯撑氧。聚合用电解装置的特点是:单室电解槽,电极间无隔膜,溶剂选用聚合物和支持电解质均可溶解,且在电解条件下也比较稳定的二氯甲烷、硝基苯和氢醌二甲醚等。本实验是用三对铂电极(2×5cm)作为电解的工作电极和副电极串联,电极间距离为1mm。参比电极为Ag—AgCl。槽中加入50ml溶液,含0.005摩尔的玢和0.01摩尔的支持电解质(如四乙基溴
2,6-Xylenol can be copper amine complex as a catalyst, react with oxygen at room temperature to generate poly-2,6-dimethyl 1,4-phenylene oxide (polyphenylene ether). This polymerization reaction can be carried out under anodic oxidation. At the same time release equivalent hydrogen. The authors have recently found that phenols can be electroxidized to poly-2,6-disubstituted phenylene oxide under suitable electrolysis conditions. Polymerization electrolysis device is characterized by: single-cell electrolyzer, no separator between the electrodes, the choice of solvent polymer and supporting electrolyte can be dissolved, and under electrolysis conditions are relatively stable methylene chloride, nitrobenzene and hydroquinone dimethyl Ether and so on. This experiment is to use three pairs of platinum electrodes (2 × 5cm) as the working electrode and the secondary electrode electrolysis series, the distance between the electrodes is 1mm. The reference electrode is Ag-AgCl. A 50 ml solution was added to the bath containing 0.005 moles of acenaphthene and 0.01 moles of supporting electrolyte (such as tetraethyl bromide
