Phase behaviour study of chalcone in dense CO2

Cyclic carbonate synthesis from CO2 and epoxides using zinc(II) complexes of arylhydrazones of β-diketones

“…The possibility of using CO 2 (a by-product of many industrial processes), as an abundant, non-flammable and non-toxic C 1 building block, is promising towards reducing fossil fuels dependence [5][6][7]. However, the high CO 2 kinetic and thermodynamic stability, mainly responsible for CO 2 successful utilization as clean solvent, poses a challenging barrier to its chemical conversion [8][9][10][11][12]. In this context, catalysis has a crucial role, which is motivating a lot of research under this topic [13][14][15][16][17].…”

Environmentally Benign Transformations of Monoterpenes and Monoterpenoids in Supercritical Fluids

“…It was found that the elevation of pressure led to an increase in the volumetric concentration of O 2 in the liquid phase (Table 3.1) [52]. There is a clear relationship between the volumetric concentration of O 2 and the kinetics of the oxidation reactions, suggesting that the solubility of O 2 in the liquid phase controls the reaction rate.…”

“…The reaction was conducted in a stainless steel autoclave and promoted by the reactor walls. The oxidation proceeded with excellent selectivity: monoepoxides 55 and 56 were found as the only oxidation products at The kinetics of epoxidation of limonene 3 using this system for different total pressures was studied in [52]. The reactions were conducted under high-pressure CO 2 (92, 99 and 102 atm) and under supercritical conditions at 120 atm.…”

Experimental Procedure for Measuring Solid–Liquid–Gas Equilibrium in Carbon Dioxide + Solute

“…It basically consists on heating or pressurizing the solvent + solute mixture in the presence of solid and fluid phases. The observation of the first drop of liquid is considered as the solid–liquid–gas equilibrium data. − …”

“…Pressure signals are sent from the transducer to a multimeter (6) and a power supply (7). The temperature is displayed in a digital thermometer (8). The expanded uncertainty 29 was estimated to be within 0.02 MPa and 0.02 K. A glass vessel (9) helps as a heat exchanger.…”
