Flash point is a very important parameter in fire protection. It is used to assess the fire and explosion hazards of liquid fuels. The determination of the flash point has practical implications for the storage, transportation and use of today's flammable liquids. For binary liquid solution, determining the flash point through the Uniquac equation is extremely difficult by calculating the parameters. In this article, the author studies the relationship between calculation by Unifac, Uniquac equation and experimentally
