摘要：

Data obtained by chromatography, adsorption from solution and theoretical calculations show that a monolayer of liquid crystal adsorbed on the surface of graphitized thermal carbon black (GTCB) has an orientational order that is analogous to the mesomorphic state of the substance. A decrease in the adsorption potential and an increase in the general structural selectivity in the separation of polynuclear aromatic and partially hydrogenated compounds were observed for the modified sorbent. This is due to the influence of the liquid crystal monolayer on the adsorption of the studied substance on the one hand, and to the influence of GTCB on the monolayer on the other. The order of elution of isomeric polynuclear hydrocarbons on the modified and unmodified surfaces is the same. which makes it easier to identify the investigated isomeric mixtures.
