Problem 6.7

Estimate the vapor pressure of acetone (mm Hg) at 50C (a) from data in Perry's Chemical Engineers' Handbook and the Clausius-Clapeyron equation, (b) from the Cox chart (Figure 6.1-4), and (c) from the Antoine equation using parameters from Table BA.

Step-by-Step Solution:

Problem 6.7

Estimate the vapor pressure of acetone (mm Hg) at 50C (a) from data in Perry's Chemical Engineers' Handbook and the Clausius-Clapeyron equation, (b) from the Cox chart (Figure 6.1-4), and (c) from the Antoine equation using parameters from Table BA.

                                                        Step by step solution

Step 1 of 3

a)

From data in Perry's Chemical Engineers' Handbook,

The value of  is not provided.

If the data fits the Clausius -Clapeyron equation, then the natural logarithmic of the partial pressure and Temperature in Kelvins  will form a linear relationship with a slope, “a” and intercept “b”.

The slope and intercept are then:

Let’s calculate the “a” and “b” values.

                                         

                                           

                                       

                                         

By using these slope and intercept values, we can calculate the partial pressure for acetone at  using this method.

                                       

               

               

             

                                              .

Therefore, estimated vapour pressure of acetone at  is 569.58 mm Hg.
