Chapter 6, Problem 6.104P

Interpretation Introduction

(a)

Interpretation:

To estimate the mass and composition (component mass fractions) of each phase of the mixtures in system 1 and in system 2.

Concept introduction:

A ternary mixture is a mixture with combination of water, acetone and methyl isobutyl ketone (MIBK). A system containing ternary mixture is divided into aqueous phase $\text{(rich}{\text{H}}_{\text{2}}O)$ and organic phase (rich MIBK)
The behavior of partially miscible three-component systems may be represented on a triangular phase diagram as follows:

Interpretation Introduction

(b)

Interpretation:

To determine the distribution coefficient of acetone in the organic phase relative to the aqueous phase for system-1 and system-2.

Concept introduction:

A ternary mixture is a mixture with combination of water, acetone and methyl isobutyl ketone (MIBK). A system containing ternary mixture is divided into aqueous phase $\text{(rich}{\text{H}}_{\text{2}}O)$ and organic phase (rich MIBK)

Interpretation Introduction

(c)

Interpretation:

To determine the selectivity, ${\text{β}}_{\text{aw}}$ of acetone relative to water in the two systems.

Concept introduction:

A ternary mixture is a mixture with combination of water, acetone and methyl isobutyl ketone (MIBK). A system containing ternary mixture is divided into aqueous phase $\text{(rich}{\text{H}}_{\text{2}}O)$ and organic phase (rich MIBK)

Interpretation Introduction

(d)

Interpretation:

To express the selectivity ${\text{β}}_{\text{aw}}$ in terms of the distribution coefficients of acetone and water, K_a and K_w . Also determine that under what circumstances might it be important to have a very high value of ß_aw.
