Flashpoint Prediction for Binary Mixtures of Alcohols with Water in Order to Improve their Safety

Aqueous solutions of alcohols are of considerable interest for a wide range of scientists and technologists. Simple dimensionless experimental formulae based on rational reciprocal and polynomial functions are proposed for correlation of the flashpoint data of binary mixtures of two components. The formulae are based on data obtained from flashpoint experiments and predictions. The main results are the derived flashpoint approximated values and the model verification by comparing the predicted values with the experimental data for the studied mixtures. Potential application for the model concerns the assessment of fire and explosion hazards, and the development of inherently safer designs for chemical processes containing binary partially miscible mixtures of an aqueous‐organic system. The flashpoint is a key factor influencing the safety behavior of flammable liquids. Simple dimensionless experimental formulae based on rational reciprocal and polynomial functions are described for correlating flashpoint data of binary mixtures. The model can be applied to assess fire and explosion hazards and to develop inherently safer designs for corresponding chemical processes.
