Extraction of acetonitrile from aqueous solutions. 1. Ternary liquid equilibriums

Liquid-liquid equilibria for ternary systems formed by acetonitrile, water, and aromatic hydrocarbons

“…For the systems acetonitrile-aromatic hydrocarbons and water-acetonitrile, the values of the parameters were obtained by submitting to regression vapor-liquid equilibrium (VLE) data of each examined binary system: In particular, two sets of Isobarlc VLE data at 28.0 and 101.3 kPa (9), for the system acetonitrile-aromatic hydrocarbons, and two sets of VLE data, one Isobarlc at 101.3 kPa (10) and the other isothermal at 60 °C (11), for the system acetronltrlle-water. The calculation procedure, described In detail elsewhere (9), was based on the minimization of the objective function, S: (5) The weighting factors FP, FT, and Fri used for each binary system are given in Table VII. acetonitrile (l)-m-xylene (3) 1 1 60 acetonitrile (l)-p-xylene (3) 1 1 60 acetonitrile (l)-ethylbenzene (3) 1 1 60 acetonitrile (l)-water (2) 0.75…”

“…Francis (3) reported in small triangular graphs the binodal curves for the systems acetonitrile-water-benzene and acetonitrile-water-toluene at 25 °C. Rao et al (4) reported complete LLE data for the system acetonitrile-water-toluene at 30 °C, and Rao et al (5) reported similar data for the system acetonitrile-water-mixture of xylenes at 31 °C.…”

Local analysis of Marangoni effects during and after droplet formation

“…However, the comparison between ACN and acetone shows that ACN exhibits a slightly faster mass transfer. The marginal difference can be explained by a slightly larger ACN mixing gap as the EFCE test system under otherwise comparable physical properties …”

“…The marginal difference can be explained by a slightly larger ACN mixing gap as the EFCE test system under otherwise comparable physical properties. [33,36,37] At constant volumetric flow _ V = 14 μL Á s −1 and concentration c ACN,0 = 10 wt% with varied droplet size (see Figure 7), the mass transfer is faster with a higher surface to droplet volume ratio at 0 mm rising height. Under the same conditions as in Figure 7, the Raman measurement inside the droplet clearly shows a similar influence of the volume to surface ratio after droplet formation (see Figure 8).…”

Sugaring‐Out Separation of Acetonitrile from Its Aqueous Solution

“…A large reflux ratio is usually accompanied by large condensing and reboiling requirements, and hence, a higher operating cost [9]. The extraction of acetonitrile from its aqueous solution by multiple solvents has also been tested [10][11][12].…”
