WebThe flash point is defined as the lowest temperature at which a liquid generates flammable vapours which can be ignited in air by a flame above its surface. The flash point is determined experimentally by heating a vessel containing the tested liquid. A flame is presented at regular intervals to the liquid surface. WebThe flash point, autoignition temperature, and heat of combustion of Acetonitrile are listed in Table 2.1. The flash points of several Acetonitrile-Water mixtures have been determined. The results are shown in Figure 2.8. Vapor mixtures of Acetonitrile and air containing between 4.4 and 16 percent Acetonitrile at 25°C are potentially flammable.
