“…In fact, mass transfer is a common transport phenomenon in liquid–liquid extraction, absorption, and distillation processes . Therefore, knowledge of the mutual diffusion coefficient of organic solvents such as ethyl acetate in water is often required in chemical industrial processes, which is fundamental for adsorption and liquid–liquid extraction processes. , In these processes, ethyl acetate is often employed because of its practical importance in the petrochemical and polymer industries . Despite the importance of the diffusional mass transfer of ethyl acetate, mutual molecular diffusion coefficient values for ethyl acetate and water system are scarce.…”

The first measured data set on the mutual diffusion coefficients of ethyl acetate–water systems over the water-rich region was reported at temperatures from 298.15 to 368.15 K. An experimental instrument has been developed and designed based on the Taylor dispersion technique to measure the diffusion coefficient in liquid mixtures. The method offers the advantages of simplicity and speed for measuring the diffusion coefficient in binary liquid systems at high-temperature conditions. The temperature and composition dependence of the binary diffusion coefficients were discussed. The mutual diffusion coefficient values for ethyl acetate–water systems are found in the range of ∼0.77–3.3 × 10–5 cm2/s with an associated average deviation range of 0.05–5%, depending on the temperature and composition of the system.
