The treatment of procedure of the chromatographic analysis of the reaction mass of cyclohexene hydrocarbomethoxylation by cyclohexanol and CO

This paper presents the gas-liquid chromatography method adaptably to the analysis of polycomponent solution modeled the composition of the reaction mass of cyclohexene hydrocarbalcoxylation by cyclohexanol and CO. The objective of the work was contained in the treatment of the procedure possessed the high accuracy and reproducability of analysis of the reaction mass. The “cyclohexene - cyclohexanol - cyclohexyl cyclohexanecarboxylate - toluene (solvent)” system was studied. The method of internal standard was selected to the calculations of the concentrations of determined components. It was found that studied ranges of the concentrations of determined substances formed the linear diapason of the work of used flame ionization detector. The calibrating coefficients for calculations of the molar concentrations from the squares of the peaks of determined components were counted. The absence of grave mistakes in the results of cyclohexyl cyclohexanecarboxylate determination and a low level of grave mistakes in determinations of cyclohexene (3.3 %) and cyclohexanol (6.7 %) were found. The estimation of confidence limits of calculated calibrating coefficients was made. The high accuracy of the chromatographic analyses (more than 98 %) and the high reproducability of the results (more than 99 %) were defined and this allows to recommend the application of treated procedure to analysis of the reaction mass of the cyclohexyl cyclohexanecarboxylate synthesis exciting an interest as possible addition to fuel and polymers.
