The synthesis of 3-bromo-4-(4-methylbenzyloxy) azobenzene (BMBOA) and
its use as a stationary phase in packed columns are described. Chromat
ographic characteristics such as column efficiency, polarity (McReynol
ds constants) and operating temperature range were studied. Retention
factors, specific retention volumes and activity coefficients for alco
hols, esters, ketones, aromatic hydrocarbons and n-alkanes were determ
ined. Phenols and 2,3, and 4-chlorobenzyl chlorides were separated on
the new phase. Based on experimental data some assumptions were made o
n the possible types of intermolecular forces between solute and solve
nt.
