Abstract

A series of homologous N, N'-bis (2, 4-dinltrophenyl)-a, w-diaminoaikanes (bis-DNP's) was chromatographed at various temperatures on r-basic chirai stationary phases derived from N- (2-naphthyl) aianine in order to determine the enthalpy and entropy of adsorption. The number of methylene groups in the bis-DNP's influences the abiiHy of the terminal r-acMlc groups to interact simultaneously with neighboring strands of stationary phase, a process ...
