Chemical Engineering: Wilson Large rammda12 rammda21

Wilson Large rammda12rammda21

Lecture note of Dr. Hiroshi Yamamoto

Please draw molecule at cyan panel. Please refer to how to use animation1, animation2.
Change atom type or delete atom, mouse down and up at the same atom.

You can calculate hydrocarbon, Alcohol, Ester, Carboxylic Acid , Keton only.

Cis-, Trans- compounds return average of both.
You need not add Hydrogen.

If you are lucky enough your browser support old JAVA and proper setting of JAVA option, you will see the window like below. Draw molecule and click Calc. button, you will get Wilson parameters.

If you can not see this window, please check browser's JAVA option or try other browser. Eventhough you fail. Give up this old IAVA verson. (This Applet is still running with Mac with FireFox browser. 2011.11.15)


Wilson Equation

D GmE/RT=-x1ln(x1+Large Rammda12x2)-x2ln(Large Rammda21x1+x2)

Large Rammda 12=V2/V1exp(-(rammda12-rammda11)/RT)
Large Rammda 21=V1/V2exp(-(rammda12-rammda22)/RT)

(rammda12-rammda11), (rammda12-rammda22) Wilson Parameter
