Weight for Thiazole

7-10 • Estimating Physical Properties for a Non-Databank Component Getting Started

Next specify the coefficients for the Antoine vapor pressure

correlation.

1 Click Properties | Parameters | Pure Component in the Data

Browser menu tree.

The object manager appears. You can see that you have filled your

TBMW parameter with scalar data.

2 Click New.

3 In the New Pure Component Parameters dialog box, select

T-Dependent correlation. A tree-style of choices appears.

4 Under Liquid Vapor Pressure, select PLXANT-1 for the

Antoine vapor pressure correlation.

5 Click OK.

The Properties | Parameters | Pure Component | PLXANT-1 |

Input sheet appears.

6 Click the Components field, select THIAZOLE.

The Antoine vapor pressure correlation (also given above) is:

ln poL

i = 16.445 - 3281.0/(T+216.255)

for poL

i in mmHg, T in °C for 69 °C < T < 118°C.

You can get help on specifying the coefficients by clicking,

then clicking PLXANT in the Parameter field near the top of this

sheet. Follow the link to Extended Antoine/Wagner.

7 Click the Temperature units field, select C.

8 Click the Property units field, select mmHg.

9 Enter the Antoine coefficients for Thiazole in the fields

numbered 1 through 9.
