Experiments were carried out to identify a solvent which has a high solubility and selectivity for methane relative to hydrogen at 295 K and pressures from 13.88 to 20.78 MPa. methane, dimethylformamide, dimethylsulfoxide, ethyl acetate, and dioxane) and non-solvents which do not dissolve PLGAs (castor oil, ethanol, decanol, diethyl ether, hexane, lactic acid, and methanol). •The solubility results also include semi-solvents, which have variable solubility for PLGA depending on the L:G ratio in the PLGA polymer. Binary solubilities with pure hydrogen and methane, and ternary solubilities with 73 mol% H 2 and 27 mol% CH 4 were measured at 295 K and for pressures from 6.99 to 20.78 MPa in various organic solvents. The solubilities of cholesterol have been determined experimentally in six solvents benzene, toluene, cyclo- hexane, 1,2-dichloroethane, trichloromethane and tetrachloromethane by a dynamic method in the temperature range 290-350 K. 3.2. Fluid Phase Equilibria, 97: 191-200. Y. Miyano, W. Hayduk, Solubility of acetylene in several polar and non‐polar solvents and solvent mixtures, The Canadian Journal of Chemical Engineering, … the hydrocarbon hexane). Solubility of cholesterol in selected organic solvents. SOL 1.2 dissolve in polar solvents (e.g. Thus, organic solvents, such as toluene and p-xylene, due to their non-polarity and the high density of aromatic π electrons which have stronger interaction with cyclic crown-shaped S 8 are good solvents for sulfur. water, alcohols) and non-polar molecules in non-polar solvents (e.g. The solubility characteristics of covalent compounds are determined chiefly by their polarity. Solubility in mixed solvents of organic compound and ionic liquid. This is why ionic compounds like table salt (sodium chloride) or compounds like sugar, dissolve in water but do not dissolve to any great extent in most organic solvents.
