酞菁键合硅胶的制备及分离取代酞菁异构体（Preparation of Phthalocyanine Bonded Silica Gel for the Separation of Phthalocyanine Isomers）
酞菁键合硅胶 制备 分离 异构体
2010/8/18
制备和表征了一种新的酞菁键合硅胶，三-β-(辛巯基)-β-(磺酰胺基)-酞菁铜键合硅胶。研究了该键合酞菁硅胶作为HPLC固定相的基本色谱性能。实验结果表明，该固定相可以分离四-α-(2，2，4-三甲基-3-戊氧基)酞菁(铜、镍)的4种异构体，也可以观察到四-α-(2，2，4-三甲基-3-戊氧基)无金属酞菁的4种异构体，而商业C18(VERTEX Eurospher)却只能观察到两组峰，表明这种酞菁...
