“…Regardless of components with very small amounts, multicomponent systems can be modeled as pseudo-ternary systems. Thus, extensive attempts have been made to determine the phase behavior of ternary mixtures of various compounds under highpressure conditions (Kurnik and Reid, 1982;Johnston and Penninger, 1989;Liu and Nagahama, 1996;Freitag et al, 2006;Fu et al, 2007;Chobanov et al, 2010;Deiters and Kraska, 2012;Sadus, 2012;Yang et al, 2012;Rebelatto et al, 2015).…”

Due to the importance of supercritical fluid technology (SFT) in different industries, it has been the subject of intense research in recent decades. Solubility is a key concept in SFT. In fact, obtaining knowledge about the theoretical concepts of solubility and related experimental measurement methods can be useful in developing and improving the quality of research in this field. This study reviews the fundamental knowledge of solubility in supercritical fluids and investigates the significant topics in this field, including high-pressure phase behavior, experimental measurement methods, modeling, and molecular simulation of solubility.

In this study, the phase equilibrium behavior of the ternary system (CO 2 + MeTHF-3-one + lauric acid) was investigated to provide insights into the enzymatic synthesis of sugar-based surfactants. Experimental data were obtained over the 313.15 to 343.15 K temperature range and at pressures of up to 13.02 MPa using a static synthetic method with a variable volume visualization cell. Three different concentrations of lauric acid for MeTHF-3-one, 0.3%, 1.3%, and 2.5 mol %, were examined. Vapor− liquid transitions were successfully observed and modeled by the Peng−Robinson equation of state with the PR-vdW2 variant. Adding lauric acid did not impact the transition pressures compared with CO 2 -MeTHF-3-one binary systems. The LCST behavior type, with increasing transition pressures as temperatures increased, was consistent across all systems studied.

“…With the development of methods for producing PLA by ROP in supercritical fluids [87] the studies of the multicomponent phase diagrams of lactide became very attractive. Thus, the binary L-lactide/CO2 [88] pseudobinary L-lactide/propane/ethanol [89] and triple L-lactide/ethanol/CO2 [90] systems were studied in detail. It should be noted that there are no investigations of glycolide, DL-and meso-lactide phase diagrams in spite of their value for biodegradable polymers.…”

Glycolide and lactide function as the commonly used diester monomers for the preparation of high-molecular weight, degradation-prone (co-)polyesters. Both glycolide and lactide-based polymers are widely used in medicine, pharmaceuticals, the food industry, and additive technologies. This review on the diesters, spanning research from 1833-1854 to the present, encompassing their structural peculiarities, physico-chemical properties, and the range of different methods for obtaining themincluding reaction mechanismsfrom lactic and glycolic acids, their esters, and halogen derivatives. The review also discusses the chemical transformations of lactide and glycolide (apart from ring-opening polymerization) into valuable organic and high-molecular compounds, such as acrylic acid, nitrogen-containing heterocycles, and functional polymers with novel properties.
