Estimate the vapor pressure of acetone (mm Hg) at 50C (a)

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.
