The flash point of liquid mixtures is discussed in problem 10.14. For the following mixtures, estimate the flash point temperature of the following components and their equimolar mixtures using UNIFAC:

(a) Methanol (LFL = 7.3%) + 2-butanone (LFL = 1.8%)

(b) Ethanol (LFL = 4.3%) + 2-butanone (LFL = 1.8%).

Data from problem 10.14

Use Raoult’s law to estimate the flash point temperature for the following equimolar liquid mixtures in an air atmosphere at 750 mmHg total pressure:

(a) Pentane (LFL = 1.5%) and hexane (LFL = 1.2%)

(b) Methanol (LFL = 7.3%) and ethanol (LFL = 4.3%)

(c) Benzene (LFL = 1.3%) and toluene (LFL = 1.27%)
