The present work is devoted to the modelling which is based on the modified Cahn-Hilliard equation, the interplay of equilibrium and
non-equilibrium phase transitions. The non-equilibrium phase transitions are modelled by the Schlögl
reactions systems. We consider the advancing fronts which combine these both transitions. The traveling wave solutions are obtained;
the conditions of their existence and dependence on the parameters of the models are studied in detail. The possibility of the
existance of non-equilibrated phase is discussed.
