Vapour‐liquid equilibria in ternary systems. VI. The system water‐acetone‐chloroform

Abstract

The heterogeneous equilibria between liquid and vapour phases in the system water-acetone-chloroform have been investigated a t a pressure of 760 mm. It appears that a saddle point occurs in the two-liquids area of this system and that in addition a minimum occurs in the liquid surface.111. The binary systems. The equilibria in these systems and also in the ternary system were A. Water-acetone.Since the compositions of the vapour and the liquid are very different, we used much liquid, so that evaporation of a small amount of it did not result in any appreciable change of the composition.Starting from water, the boiling point first falls very steeply with increasing acetone content, afterwards much less steeply and again determined at a pressure of 760 mm. 8 ) P.

Nonrandom Two-Liquid Segment Activity Coefficient Model with Association Theory

“…Figure 13 shows the association model predicts the ternary LLE phase envelope very close to the experiment data. 30 The NRTL model is capable of predicting the ternary LLE phase envelop with a similar accuracy with the three pairs of binary interaction parameters regressed from VLE or LLE data of the three binary systems. On the other hand, the original model significantly under-predicts the immiscible region of the ternary LLE because of its inadequacy in describing the cross-association between acetone and chloroform.…”

Energy efficiency of acetone, butanol, and ethanol (ABE) recovery by heat-integrated distillation

“…The exchanger area of condensation and the diameter of columns increase a lower pressure of operation. However, this effect is not necessary true in the acetone column (C2), due to the increase of acetone volatility at low pressures [31][32][33] (Fig. 4).…”

In situ multi-modal monitoring of solvent vapor swelling in polymer thin films

“…The vapor volume ratio differs from the liquid volume ratio in accordance with the boiling points of each solvent and their interactions, and the behavior seen is consistent with the previous reports. 30,31 Mixed vapors can alternatively be prepared using separate solvent reservoirs. When acetone and chloroform are held in separate containers, the vapor volume ratio of each component can be straightforwardly controlled by varying the volumetric flow in each channel.…”
