“…For erythritol, Hao et al (2005) report a 4 % uncertainty by comparing with literature data. For pentaerythritol, we found by comparing data of Cheon et al (2005), Chianese et al (1995) and Mullin (2001) that the RMSRD on room temperature x sat s is 5 %. Compared to the estimated errors on solid state pressure (see Sect.…”

Abstract. Henry's law constants (HLC) are derived for several polyols bearing between 2 and 6 hydroxyl groups, based on literature data for water activity, vapour pressure and/or solubility. While deriving HLC and depending on the case, also infinite dilution activity coefficients (IDACs), solid state vapour pressures or activity coefficient ratios are obtained as intermediate results. An error analysis on the intermediate quantities and the obtained HLC is included. For most compounds, these are the first values reported, while others compare favourably with literature data in most cases. Using these values and those from a previous work (Compernolle and Müller, 2014), an assessment is made on the partitioning of polyols, diacids and hydroxy acids to droplet and aqueous aerosol.

“…For xylitol, Wang et al (2013) reported an error of no more than 0.5 % on x sat s . For pentaerythritol, a 0.3 % error can be derived from the study of Cheon et al (2005) and 0.15 % from the study of Chianese et al (1995). Higher errors are found when comparing different studies.…”

“…The ranges of variation for the growth and nucleation rate orders were selected to incorporate the experimentally estimated kinetic parameters from the literature. 11,33,[42][43][44][45][46][47][48][49] By varying the orders, the CSD in the product effluent stream can be determined when each order is higher or lower than 1. The range of variation of the stage number was one to ten, even though the stage number would generally not be more than six.…”

Continuous multistage MSMPR crystallization processes are useful for the large scale production of particulate systems. However, the design of operating strategies to meet specific objectives and materials has not been entirely investigated. In this work, the effect of important crystallization kinetic parameters on the optimal operating strategy was examined. The important parameters are the kinetic constants of the primary and secondary nucleation rates, the orders of the nucleation and growth rates, and the number of crystallizer stages. The analyses revealed that a drastic cooling strategy in the primary nucleation dominant region and linear cooling in the secondary nucleation dominant region are best for producing large particle sizes. A stage number of around three is effective in both regions.These results can be utilized to roughly determine the operating strategy for a process, if the crystallization kinetic parameters are already roughly known.

Solubility Measurement and Data Correlation of Pentaerythritol in Four Binary Solvent Systems at Temperatures from 283.15 to 323.15 K

et al. 2021

The solubility of pentaerythritol (PE) in four binary solvents (methanol + water, ethanol + water, isopropanol + water, acetonitrile + water) is determined using the gravimetric method at temperatures ranging from 283.15 to 323.15 K under 0.1 MPa. The experimental results demonstrate that the solubility of PE increases with the increase of temperature in all four binary solvent systems. And water has a relatively positive effect on the solubility of PE in all four binary solvents. However, the solubility of PE in ethanol + water and isopropanol + water mixtures first increases with the increase of the ethanol/isopropanol fraction and then decreases when the temperature exceeds 303.15 and 288.15 K, respectively. And the solubility reaches the maximum when the initial mole fractions of ethanol/isopropanol of the binary solvent are 0.2. Besides, experimental solubility is fitted with three thermodynamic models including the modified Apelblat model, λh model, and CNIBS/R-K model, and all of the average relative deviation (ARDs) are less than 4%, indicating good accordance with the experimental results. In addition, among the three thermodynamic models, the CNIBS/R-K model has the best fitting performance, in which all of the ARDs are less than 1.7%.
