Feature analysis of vapor-phase chromatography of high boiler organic compounds
V.M. FarzaliyevThe paper presents the physical-chemical features of the vapor-phase chromatography method for the analysis of polar high boiler organic compounds. The application conditions of vapor-phase chromatography for the research of petrochemical synthesis products are analyzed. The mechanism of chromatographic seperation of compounds in the vapor-liquid-solid phase system is reviewed. The physical-chemical parameters of application of vapor-phase chromatography are provided. It is shown that liquid crystals can be used for the efficiency increase of the analysis of high boiler organic compounds as hard carriers. Thus, isomer compounds in the flow of water steam may be seperated. The usage of water-formamide mixture as a gas carrier enables the analysis of high boiler amine-based organic compounds. Natural, modified zeolite-containing tuff, diatoms and zeolites can be used as adsorbents and hard carriers in the separation of high boiler products of petrochemical synthesis.
