Various partial miscibilities of binary liquid mixtures predicted by the extended Flory-Huggins lattice theory are shown in this article, and the mathematical conditions for each partial miscibility are obtained. And in terms of the theory it is shown that the unusual partial miscibility of water-2-butanol system can occur.
