Ternary liquid mixtures are important in many engineering applications. The study of flash point for ternary flammable solutions of liquid is of great significance in fire prevention to ensure the safety of dangerous flammable liquids and when conducting fire fighting. Experimental data were obtained using a Pensky - Marten closed-cup tester and calculated using an approximate model using equation Wilson, Uniquac, NRTL or Modified UNIFAC methods.
