THE ANOMALOUS CHROMATOGRAPHIC RETENTION BEHAVIOR OF N-METHYL CARBAZOLE IN GAS CHROMATOGRAPHY

Ⅰ. INTRODUCTION The relationships between the chromatographic retention values of a compound, its molecular structure, and its intermolecular interaction with the stationary phase have been more and more extensively studied, The study of the retention behavior of a compound not only reveals the above carrelation, but also suggests a new way for investigating the physicoehemical basis of the chromatographic process. Carbazole and its derivatives are well-known excellent photoelectrical materials. Thus their physico-chemical properties have attracted wide attention.

守望船政人

为挖掘整理船政文化,福州市2019届市管引进生(清华、北大、人大)与马尾中国船政文化管委会、马尾船政文化研究会、福建船政文化交流协会等联合发起"福州船政文化口述历史计划",至今已对十几位早期船政工人进行了采访。本文系联合采访组对林键的采访成果。林键出生于五代海军世家,长期以来专注于船政文化研究、保护、开发,以一己之力创办《船政文讯》,并聚焦基督教史研究和马尾地方文史研究,为船政文化研究、保护和开发做出了贡献。
