Abstract:
Large amount of byproduets ( 1,4-Butylene glyeol and Diethylene glyeol) are generated in theprocess of eoal glyeol. The basie data were inadequate for separation and purifieation proeess design. We usedonly vapor phase cireulation method to measure vapor-liquid equilibrium values of 1 ,4-Butylene glyeol and Di.ethylene glyeol at 6. 67KPa. Thermodynamie consisteney test was conducted with area test method, and theexperimental data of the binary system measured in our work passed the test. WLSON and NR’Tl activity coef.ficient models were respectively applied to correlate the experimental data. The results showed that these twomodels both had very small deviation from the experimental results, which can meet the separation require.ments of the process.
