Abstract
Retention data are recorded for nineteen groups of isomeric disubstituted benzenes on the stationary phases Apiezon L, dinonyl phthalate, polyethylene glycol—stearic acid, tritolyl phosphate, 2,4,7-trinitrofluorenone and silicone gum rubber. The conditions for the accurate determination of the ortho-:meta-:para-ratios of many of these mixtures are reported, and the particular applications of each of the liquid phases examined are discussed.
