【Abstract】 By using the small-typed gas-liquid equation kettle, the experimenter obtained the gas-liquid balance data of binary mixture of ethanol and normal propyl alcohol in different density and gained their equation relationship by way of subsection function method of interpolation;the mathematical model was set up according to different operative methods of batch rectification and the general computer program was designed with it.The accuracy and practicability of the calculating method was validated by separating ethanol and normal propyl alcohol with batch rectification.更多还原
