| Abstract: | In this work,by adopting modified Dvorak-Boublik equilibrium still ,and usingmethods of micro-distillation,gas chromatraphy analysis combined with technique of simulat-ed true boiling point distillation with gas chromatography for sample analysing,the VLE datawere determined at normal pressure for seven systems of methyl ethyl ketone-wax(contain-ing paraffin oil),benzen-wax,toluene-wax,acetone-lubricant fraction,methyl ethyl ketone-lubricant fraction,benzen-lubricant fraction and toluene-lubricant fraction. Tbedata werecorrelated by pseudo-component method combination with model of Chao-Seader.The resultsare satisfactory otherwise than this three systems of methyl ethyl ketone-wax ,acetone-lubri-cant fraction and methyl ethyl ketone-lubricant faction. |
