In this study Flash point for pentan-1-ol + water + cyclohexanon mixture and its binary set
mixtures were measured by equilibrium test method using the tagged close cup analyzer. The
binary interaction parameters for NRTL and UNIQUAC activity coefficient models were
calculated via Le Chatelier rule. Newton forward method was used to optimize parameters. The
calculated parameters were validated by applying them to calculate the flash point of pentan-1-ol +
water + cyclohexanon ternary mixture and comparing the results with experimental data. The
results showed that the calculated parameters could be used to predict the flash point of ternary
mixture with close agreement with experimental data
