Study of solvents for butadiene extraction by gas chromatography

Six solvents have been studied by GLC for separation of 1,3-butadiene from C4-olefins having close boiling points. Infinite dilution activity coefficients and partition coefficients of five olefins have been determined in these solvents by conventional GLC-technique at 30 °C. Relative volatilities of olefins in solvents have been calculated and on this basis the solvents have been compared.
