COSMOSPACE
COSMOSPACE is an activity coefficient model in which the activity coefficient of the components in a
liquid chemical mixture can be related through their molar fraction. It was initially developed as an implicit solution to COSMO-RS.
While UNIQUAC is a first order approximation, COSMOSPACE gives the exact solution of a lattice model in which pairwise molecule surfaces interact. Therefore, COSMOSPACE outperforms Uniquac in the description of vapor–liquid and liquid–liquid phase equilibria.
