Verification of Pure Component Parameters

2) In the last year the parameters were refitted using available experimental data. But of course poor results occur also for other pure component properties and 

3) A further example with poor default parameters is given in Appendix F.

Calculate the separation factor for the system acetone (1)-water (2) at infinite dilution (xi = 1) (top of the column) at the normal boiling point of acetone (Th = 56.27 C). For the calculation, the following value of the activity coefficient at infinite dilution = 5.3 (measured at 55.3 C by Bergmann and Eckert [9]) should be applied. 

The separation factor at infinite dilution in pure acetone can directly be calculated (see Chapter 5.4). Since the vapor pressure of acetone at the normal point is 760 mmHg, only the vapor pressure of water at 56.27 C is required additionally
