Solubilities and partial molar volumes of N,N′-dibutyl-oxalamide, N,N′-dihexyl-oxalamide, N,N′-dioctyl-oxalamide in supercritical carbon dioxide

Solubilities and partial molar volumes of new CO2-philic propane derivatives in supercritical carbon dioxide

“…However, solubility data under high and low temperature in scCO 2 are less frequently reported [12][13][14][15]. Furthermore, CO 2 is a non-polar molecule with a low dielectric constant, which prevents it from dissolving hydrophilic compounds with high polarity, metal ions and high-molecular-mass compounds [16][17][18][19][20][21][22][23][24][25][26][27]. One solution to enhance the solubility is to introduce some CO 2 -philic compounds into the scCO 2 system.…”

Solubility comparison and partial molar volumes of 1,2-hexanediol before and after end-group modification by methyl oxalyl chloride and ethyl oxalyl monochloride in supercritical CO2

“…Haence accurate solubility data testing is necessary [9][10][11]. Generally, the solubility of compounds depends on their groups of molecular structure, especially the end groups, and the molar mass [12][13][14].…”
