“…The relationship between solubility and temperature can be presented by eq based on the activity coefficient model , where x is the mole fraction of TOPAP, γ is the activity coefficient of TOPAP, T is the absolute temperature, T m is the melting point of TOPAP, and Δ fus H tp is the melting enthalpy. Δ C p and Δ V are corrections of the heat capacity and pressure; the terms are generally negligible.…”

Solubility of 3,7,9,11-Tetraoxo-2,4,6,8,10-pentaaza[3.3.3] Propellane (TOPAP) in Different Pure Solvents at Temperatures between 273.15 and 318.15 K

propellane (TOPAP) was measured in pure H 2 O and 11 other organic solvents, including methanol, acetonitrile, acetone, ethyl acetate, ethanol, tetrahydrofuran, n-propanol, i-propanol, dioxane, ethylene glycol, and toluene in the temperature range from 273.15 to 318.15 K at an interval of 5 K by the equilibrium method with ultraviolet detection. For all reagents selected, the results showed that the solubility data of TOPAP increased with increasing temperature. All of the obtained experimental results in all mentioned solvents were correlated with temperature by using the ideal solution model, Apelblat model, Yaws model, λh equation, and NRTL model. The ideal solution model, Apelblat model, Yaws model, and λh equation are more suitable for the correlations of solubility of TOPAP, and they have a smaller maximum relative average deviation.

“…For real solutions, a better approach for a binary or multicomponent system is to adjust the equation to replace the heat of fusion by the heat of solution (Nývlt et al, 2001) to consider solvent -solute interactions: This equation is traditionally used to adjust solidliquid equilibria (see, e.g., Noubigh and Oueslati, 2017;Bhesaniya and Baluja, 2014;Shi et al, 2016;Li et al, 2012;Baluja, 2012). Hence, the heat of solution can be calculated from the integration of Eq.4 to give Eq.…”

L-menthol is an essential oil produced from Mentha arvensis. An experimental L-menthol solidliquid equilibrium in menthol oil constituents was determined in the temperature range between 271 K and 300 K, by the method of creating a saturated solution at a given temperature by using an excess of crystals in the suspension. The mole fraction of the experimental data, on a logarithmic basis, were fitted against T by the Apelblat equation and by a linear equation with good results. The equations were: ln(x) = [-52.45 + 1,170.70/T + 8.48.ln(T)] and ln(x) = 3.98 -1,249.65/T with T in K. Both equations give a good correlation with the experimental data. From the Apelblat equation the enthalpy of solution was also calculated as a linear function of temperature and has an average value of 150.31 J/mol in the temperature interval studied.

“…The modified Apelblat equation is frequently used to monitor the correlation of solubility and temperature in solid-liquid equilibrium. Most systems that are composed of solute and solvent could be preferably fit well with the modified Apelblat equation 6,7,8 . The Buchowski-Ksiazaczak ëh equation is an alternative method to describes the solid-liquid equilibrium behavior by only two adjustable parameters, λ and h, that firstly developed in an eutectic system of solute in saturated solution 9 .…”

Purification process of erythritol in industrial production are currently composed of multiple steps. To improve the purification efficiency and to operate the working condition precisely, the solubility property of erythritol should be monitored. In this study, the erythritol solubilities in aqueous solvents including methanol, ethanol and 2-propanol were experimentally measured by using the gravimetric method within the temperature range of 273.15 K to 283.15.15 K (with 2 K interval) and 283.15 K to 323.15 K (with 10 K interval). The experimental results showed that erythritol solubility increased due to the increase of temperature but decrease of mass fraction of organic solvent. The solubility was also depended on polarities of solvents. The lowest solubility was obtained when using aqueous ethanol. To generate solubility model of erythritol, Apelblate equation, Buchowski-Ksiazaczak λh equation and Van't Hoff model were applied to explain correlation and behavior of erythritol solubility. Based on statistical analysis, Apelblate equation obtained the best correlation to the experimental data compared to Buchowski-Ksiazaczak λh equation and Van't Hoff model. The solubility model with the estimated parameters could be further applied for optimizing purification processes of erythritol in industries.
