| Summary: | 碩士 === 國立成功大學 === 化學工程研究所 === 83 === In this work ,we used an apparatus of semi-flow type to
measure the vapor-liquid equilibrium.The solubilities of carbon
dioxide,carbon monoxide or dimethyl ether in 1,4-butanediol
were measured at 25,50,100 ℃. Along each isothermal, the
carbon dioxide + 1,4-butanediol system was measured at
pressures from 11.68 to 51.68 atm , the carbon monoxide
+1,4-butanediol system was measured at pressure from 21.68 to
51.68 atm,and the dimethyl ether + 1,4-butanediol system was
measured at pressures from 1.34 to 4.40 atm. We used two
equations of state ( SRK and PR EOS) with traditional mixing
rules to correlate the experimental data of carbon dioxide
, carbon monoxide or dimethyl ether in 1,4-butanediol
and to determine the the values of the interaction
parameter Kij. By way of the experimental data , the Krichevsky-
Kasarnosky equation was used to calculated Henry's
constants and the partial molar volumes at infinite dilution .
Finally,what we did will be developed to correlate the
vapor-liquid equolibrium relations of carbon dioxide , carbon
monoxide or dimethyl ether in 1,4-butanediol.
