- Description
- In the present article, the experimental flash points (FPs) of partially miscible and non-ideal mixtures including 3-pentanol + water, 2-pentanol + water, and 1-hexanol + water are reported for the first time. The measured FPs were predicted based on the vapor pressure concept and thermodynamic equilibrium. The cubic-plus-association (CPA) equation of state (EoS) along with the CR-1 combining rule and Elliot combining rule (ECR) were used to investigate the non-ideality of investigated systems. In the following, the same method was used with the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) EoSs to evaluate whether simpler EoSs can accurately predict the FPs of non-ideal mixtures. Therefore, in addition to 3-pentanol + water, 2-pentanol + water, and 1-hexanol + water, numerous totally and partially miscible aqueous-organic systems containing 1-pentanol, isobutanol, 2-butanol, 1-butanol, isopropanol, propanol, ethanol, and methanol were studied in terms of FP prediction. The findings indicated that SRK is marginally more effective than PR. Moreover, SRK EoS was almost as effective as the CPA EoS with the CR-1 combining rule. The CPA EoS that used ECR, on the other hand, was far superior to the SRK and PR EoSs. To the best of our knowledge, CPA parameters for 2-pentanol, 3-pentanol, and 1-hexanol were calculated and reported for the first time.
