deep eutectic solvents effect on vapor liquid phase equilibrium for separation of Allyl Alcohol from its aqueous solution
Journal of Molecular Liquids, 2019Co-Authors: Haihua Jiang, Jun Gao, Baotao Diao, Lianzheng Zhang, Yinglong WangAbstract:Abstract Allyl Alcohol and water can form an azeotrope with the minimum boiling point. To separate Allyl Alcohol from its aqueous solution by distillation, the deep eutectic solvents (DESs) were applied to eliminate the azeotropic point. Two DESs choline chloride: glycerin (mole ratio of 1:1) and choline chloride: urea (mole ratio of 1:2) were selected. To validate the selected DESs for separation of Allyl Alcohol from its aqueous solution, the isobaric vapor-liquid equilibrium (VLE) data for the system of Allyl Alcohol + water + DESs were measured at pressure of 101.3 kPa. The relative volatility of Allyl Alcohol to water increased significantly by adding the DESs. With increasing the concentrations of the DESs, the azeotropic point of the system Allyl Alcohol + water moved and the azeotropic point was broken at last. Then, the COSMO model provides some theoretical insights into the separation mechanism. Meanwhile, the experimental VLE data were correlated by the NRTL model and the correlated results agreed with the measured data.

isobaric vapor liquid phase equilibrium measurements for Allyl Alcohol with chloroform ethyl acetate and methyl propionate at 101 3 kpa
Journal of Chemical & Engineering Data, 2019Co-Authors: Baotao Diao, Jun Gao, Ke Wang, Lianzheng Zhang, Yinglong WangAbstract:For separation of the azeotrope Allyl Alcohol and water by azeotropic distillation, chloroform, ethyl acetate, and methyl propionate were selected as the azeotropic agents. In this work, the vapor–liquid phase equilibrium (VLE) data for the binary systems (Allyl Alcohol + chloroform/ethyl acetate/methyl propionate) were measured at 101.3 kPa using a modified Rose still. The VLE experimental data were checked by Herington and van Ness methods to verify the thermodynamic consistency. The excess Gibbs energy GE was calculated to evaluate the nonideality for three binary systems. Meanwhile, three thermodynamic models nonrandom two-liquid, universal quasichemical, and Wilson were adopted to correlate the experimental data, and the binary interaction parameters of the three models were regressed. The root-mean-square deviations of vapor composition (y1) and equilibrium temperature (T) are less than 0.0057 and 0.18 K, respectively, which indicates that the experimental data were well correlated by three models.

measurement and correlation of isobaric vapor liquid equilibrium for binary systems of Allyl Alcohol with isobutyl acetate butyl acetate and butyl propionate at 101 3 kpa
Journal of Chemical & Engineering Data, 2018Co-Authors: Yangchen Gao, Jun Gao, Puyun Shi, Zhishan Zhang, Yinglong WangAbstract:For separation of the azeotrope of Allyl Alcohol and water, three extractive agents—isobutyl acetate, butyl acetate, and butyl propionate—were selected to extract Allyl Alcohol from the azeotrope. To recover the extractive agents by distillation, the isobaric vapor–liquid phase equilibrium (VLE) data for Allyl Alcohol + isobutyl acetate, Allyl Alcohol + butyl acetate, and Allyl Alcohol + butyl propionate were measured at 101.3 kPa. With the VLE data, there is no azeotrope formed in three systems. The consistency of the measured VLE data was validated by the Herington, infinite dilution, pure component consistency, and van Ness tests. Moreover, the Wilson, UNIQUAC, and NRTL models were used to fit the measured VLE data. All of the calculated results agreed with the VLE experimental data. Meanwhile, the parameters of the Wilson, UNIQUAC, and NRTL were regressed, which can be employed for the development and optimization of the separation process. Furthermore, the VLE data were predicted by the UNIFAC model ...

salts effect on isobaric vapor liquid equilibrium for separation of the azeotropic mixture Allyl Alcohol water
Fluid Phase Equilibria, 2018Co-Authors: Puyun Shi, Jun Gao, Kai Zhang, Yinglong WangAbstract:Abstract Allyl Alcohol and water can form an azeotrope with the minimum boiling point. To separate the azeotrope of Allyl Alcohol and water by salt distillation, three salts calcium chloride, calcium nitrate and magnesium nitrate were selected to break the azeotrope. The vapor-liquid equilibrium (VLE) data for the systems Allyl Alcohol + water, Allyl Alcohol + water + calcium nitrate, Allyl Alcohol + water + calcium chloride and Allyl Alcohol + water + magnesium nitrate were measured at pressure of 101.3 kPa. The results indicated that the relative volatility of Allyl Alcohol to water increased by adding the salts at the molar fraction of Allyl Alcohol higher than 0.2. With increasing the concentrations of the salts, the azeotropic point of the system Allyl Alcohol + water moved. When the concentrations of calcium chloride and magnesium nitrate were 0.10, 0.15, respectively, the azeotropic point was broken. The effect of salts on the azeotropic point of the system Allyl Alcohol + water follows the order: calcium chloride > magnesium nitrate > calcium nitrate. Moreover, the experimental VLE data were correlated by the NRTL model. All the root-mean-square deviations for the temperature (T) and the mole fraction of the vapor phase (y1) between the measured and calculated data were less than 0.26 K and 0.005, respectively. Meanwhile, the binary interaction parameters of the NRTL model were regressed.

Journal of Chemical & Engineering Data, 2016Co-Authors: Lianzheng Zhang, Jun Gao, Yangchen Gao, Zhishan Zhang, Dhakal PratikAbstract:Isobaric vapor–liquid equilibrium (VLE) data for three binary systems of (Allyl Alcohol + water), (Allyl Alcohol + methanol), and (Allyl Alcohol + ethanol) were measured at atmospheric pressure of 101.3 kPa by a modified Rose vapor recirculating type equilibrium still. The thermodynamic consistency test for the experimental data of the three binary systems containing Allyl Alcohol were checked by Herington method and van Ness test, respectively. Meanwhile, the measured VLE data were correlated by three activity coefficient models of Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC), for which all of the calculated results showed good consistency. The binary interaction parameters of the models were also regressed. The azeotropic behavior could not be observed in (Allyl Alcohol + methanol) and (Allyl Alcohol + ethanol) systems, but for (Allyl Alcohol + water) system, the azeotropic behavior was found, and it had the minimum azeotropic point.

participation of different cell types in the restitutive response of the rat liver to periportal injury induced by Allyl Alcohol
Journal of Hepatology, 1999Co-Authors: Li Yin, David Lynch, Stewart SellAbstract:Abstract Background/Aim: Restitution of periportal liver necrosis induced by Allyl Alcohol involves proliferation and differentiation of putative liver stem cells. The participation of different non-epithelial cell types required to restore the liver cord structure in this process has not been well documented. The aim of the study was to determine the anatomic relationships among cells of liver lineage, extracellular matrix, and non-parenchymal cells during repair of periportal liver injury. Methods: Periportal liver injury in rats was induced by intraperitoneal injection of Allyl Alcohol. Cells of the liver lineage, as well as Kupffer cells, hepatic stellate cells, macrophages, and the extracellular matrix components fibronectin and laminin were localized using immunohistologic methods for 7 days after injury. Results: During the first day there was loss of periportal hepatocytes, as well as sinusoidal nonparenchymal cells, including macrophages, Kupffer cells and hepatic stellate cells. After day 1 macrophages appeared within the necrotic zone, increased until days 3–4, and then decreased to a few cells within reappearing sinusoids. At days 2–5 there was first proliferation of small "null" intraportal cells, which later acquired markers of ductular (OV-6, CKPan ) and liver cell differentiation (alphafetoprotein, carbamoylphosphate synthetase-I), eventually assuming mature hepatocyte morphology. There was also moderate bile duct hyperplasia with extension of small newly-formed ducts from the intraportal zone into the immediate periportal zone. Kupffer cells and hepatic stellate cells became enlarged at the borders of the necrotic and non-necrotic central zone and then appeared to migrate into the oval cell population expanding across the periportal zone. During therestitution phase, hepatic stellate cells were closely associated with the proliferating oval cells, surrounding small aggregates of oval cells which appeared to be forming liver cords. Kupffer cells also stained for fibronectin, and fibronectin was seen at the intersection of the injured portal and uninjured central zones and around the expanding oval cells. In some intraportal zones, the laminin surrounding the bile ducts was lost. It was speculated that this may permit proliferating ductular cells to migrate out of the bile ducts into the periportal zone. By days 6 and 7 most of the injured liver was restored to normal, with a few foci of chronic inflammation remaining. Conclusions: There is a close anatomic relationship between immature liver lineage cells (oval/duct cells) and non-parenchymal cells during the restitutive repair of periportal injury. The nature of this relationship to the possible production of growth factors and expression of growth factor receptors by the cells involved during the restitution process is discussed.

participation of small intraportal stem cells in the restitutive response of the liver to periportal necrosis induced by Allyl Alcohol
Hepatology, 1995Co-Authors: Leonid Yavorkovsky, Eva Lai, Zoran Ilic, Stewart SellAbstract:Abstract To determine the involvement of different hepatocyte populations in response to periportal injury, the restitutive response to Allyl Alcohol (AA) injury was examined. Adult female Sprague-Dawley rats were injected intraperitoneally (IP) with 0.62 mmol/kg AA, killed at 6, 9, 12, 33, 57, 81, and 153 hours after injection, and the livers were examined for injury and for restitutive proliferation by histology, autoradiography, and immunohistochemistry to detect alpha-fetoprotein (AFP), glutathione-s-transferase-p (GST-p), desmin, leukocyte common antigen, albumin, and monoclonal antibodies to liver cells: OV-6, H-4, and T-6. AA produces variable periportal liver necrosis predominantly at 6 to 12 hours. Proliferation of hepatocytes throughout the hepatic cord is seen early after injury in nonnecrotic areas: predominantly in zone II, but also in zones I and III, including some cells adjacent to the central vein. Within 2 to 3 days the necrotic zones are filled with small cells and by 1 week the liver architecture is essentially restored. During the active restitutive reaction from the immediate periportal rim the following cell phenotypes are seen: null cells: → (AFP+, OV-6−, GST-p−) cells → (AFP−, OV-6+, GSTp+) cells → large (AFP−, OV-6−, GST-p−, H-4+) liver cells. Albumin staining was negative. We conclude that restitutive proliferation of periportal necrosis induced by AA appears to be accomplished by proliferation of intraportal (?stem) cells whose progeny differentiate and eventually repopulate the necrotic zone.
