Division 2.6.4.3

One suitable method is described in Gmehling and Rasmussen (Ind. Eng. Fundament, 21, 186, (1982)). For a mixture containing non-volatile components the flash point is calculated from the volatile components. It is considered that a non-volatile component only slightly decreases the partial pressure of the solvents and the calculated flash point is only slightly below the measured value.
