A comparative study of the volumetric properties of dilute aqueous solutions of 1-propanol, 1,2-propanediol, 1,3-propanediol, and 1,2,3-propanetriol at various temperatures

Experimental determination and modeling of excess molar volumes, viscosities and refractive indices of the binary systems (pyridine+1-propanol, +1,2-propanediol, +1,3-propanediol, and +glycerol). New UNIFAC-VISCO parameters determination

“…Chemicals were kept in dark bottles in an inert atmosphere, used without further purification and degassed just before a sample preparation. In table 1 densities, dynamic viscosities and refractive indices of pure substances have been compared with literature values at several temperatures [15][16][17][18][19][20][21][22][23]. The agreement between literature and our experimental values is very good with differences less than 0.3 kg Á m À3 for density measurements, in most cases within 8 Â 10 À4 for refractive indices and within 1 Â 10 À2 mPa Á s for viscosity measurements of less viscous fluids.…”

Viscosity and surface tension of glycerol + N-methyl-2-pyrrolidone mixtures from 293 to 323 K

“…[2] Glycerol and N-methyl-2-pyrrolidone were added to water for enhancing the solubility of low water-soluble pharmaceuticals and also used as their individual or mixtures for various purposes. [3][4][5][6][7][8][9][10][11] The viscosity and/or surface tension of glycerol [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] and N-methyl-2-pyrrolidone [28][29][30][31][32][33] have been reported in the literature. To the best of our knowledge, there is no report on the properties of glycerol + N-methyl-2-pyrrolidone mixtures in the literature.…”

Study on Thermodynamic Properties for Binary Systems of Water + L‐Cysteine Hydrochloride Monohydrate, Glycerol, and D‐Sorbitol at Various Temperatures

“…Aqueous solutions of alcohols and polyols have attracted a good deal of attention of the scienti�c community for decades for their unusual nonideal behavior, especially in the low-concentration range. Besides, their study gives important information about the nature of interactions between nonpolar and polar groups with water and how these interactions affect the balance between hydrophobic and hydrophilic effects [4][5][6][7].…”
