In this article, the combustion characteristics of different carbonate mixed solvents are considered by means of cone calorimeter. The coexistence system is composed of ternary carbonate mixed solvent and 1-g 2325 separator. Then, the comparison between coexistence systems and corresponding solvent mixtures is conducted. Experimental findings reveal that the combustion hazard of solvent mixtures is dominated by the component which is more volatile. The 2325 separator is not completely combusted when added to the ternary mixed solvent. The effects of 2325 separator on combustion of four ternary carbonate mixed solvents are different. It can be sure that the hazard posed by the addition of 2325 separator is all increased. More details about these variations have been analyzed.
