合成了十六烷基三苯基氯(溴)化鏻、四苯基氯(溴)化鏻等4种Ph_3■R■型季鏻盐,用乙酸乙酯重结晶进行纯化。对其结构用红外光谱、元素分析或核磁共振进行确证。
Four kinds of Ph_3 ■ R ■ -quaternary phosphonium salts such as cetyltriphenylphosphonium chloride and tetraphenylphosphonium chloride were synthesized and purified by recrystallization from ethyl acetate. Its structure is confirmed by infrared spectroscopy, elemental analysis or nuclear magnetic resonance.
