UNIQUAC parameters for ethylene glycol-water mixture at different temp
UNIQUAC parameters for ethylene glycol-water mixture at different temp
(OP)
Dear colleagues,
I got few questions and would appreciate your reply
For the UNIQUAC model
Water parmeters (1):
r= 0.92 and q = 1.14, q'=1.4
ethylene glycol parmeters (2)
r = 2.4088 and q = 2.2488, q'=0.4761 (could anybody confirm?)
I need to find the the binary parmeters (a12 and a21) at 30, 40, 55 and 70 deg C.
Any suggestions (articles, softwares etc)?

......dhchema wants $50 euro..........and I don't have Aspen.........any other source (handbook/website) that is cheaper or free?

Most university, and many company, libraries will have the Dechema books. Most public libraries (in the UK at least) will have a go at finding you a copy. Otherwise, is what you're trying to do really not worth 50 euro?
