摘要：

Critical-mixture curves for 13 CO2-solvent binary mixtures were estimated using the peak-shape method.(1) Mixture critical points were determined within 1 degrees C and 1 atm. The results for CO2-toluene and CO2-methanol were compared to previously reported data from high-pressure view cell studies. No more than a 3% difference was observed in the data generated by the two different techniques. A few abnormalities encountered while using the peak-shape method are also discussed.
