An alternative model of phase-separating reactive mixtures is proposed. In this model both phase separation and chemical reactions simultaneously take place and a traveling coherent structure can be formed through a Hopf bifurcation at a finite wave number. Numerical simulations show that, depending on the parameters, either lamellar or hexagonal structures travel at constant speeds in two-dimensional systems.
