利用煅烧法合成了Cu₃P,以水为氧源探究其在碱性条件下对4-甲氧基苄胺脱氢氧化反应的催化性能。结果表明,在0.1 mol/L KOH中,4-甲氧基苄胺被氧化为4-甲氧基苯甲腈,选择性达到98.9%,法拉第效率为99.1%。4-硝基苯酚被还原为4-氨基苯酚,选择性为100%,法拉第效率为96%。同时,对乙腈进行还原,基本没有副产物,全部转化为乙胺,最后进行耦合全反应体系。

Cu₃P is synthesized via calcination method,and its catalytic performance for the dehydrogenation and oxidation of 4-methoxybenzylamine under alkaline condition is investigated with water as oxygen source.It is shown that 4-methoxybenzylamine is oxidized to 4-methoxybenzonitrile in 0.1 mol·L^-1 KOH solution,with a selectivity of 98.9% and a Faraday efficiency of 99.1%.4-Nitrophenol is reduced to 4-aminophenol with a selectivity of 100% and a Faraday efficiency of 96%.In addition,there is hardly by-product when acetonitrile is reduced over Cu₃P,all acetonitrile is converted into ethylamine,and finally coupled the whole reaction system.
