Classification of the solvent properties of common liquids

Enhanced extraction yields and mobile phase separations by solvent mixtures for the analysis of metabolites in Annona muricata L. leaves

“…The selection of each solvent was made considering the solvent selectivity triangle, first described by Snyder [21] and Rohrschneider [22], since solvents from different groups in the triangle have different selectivity characteristics. These solvents are classified according to their ability to interact with the solute as a proton donor (basicity, b), as a proton acceptor (acidity, a) or a dipole (dipolarity, p), as shown in Fig.…”

Assessment of the Role of Local Strawberry Rhizosphere—Associated Streptomycetes on the Bacterially—Induced Growth and Botrytis cinerea Infection Resistance of the Fruit

“…The activity of extracts prepared with methanol were observed to have less inhibitory activity than the ethyl acetate extracts, with C3-MeOH and K5-MeOH losing all inhibitory action. The extracts prepared with methanol were also observed to possess a K2 K3 K5 S4 S5 S21 C2 C3 C6 P2 P4 P7 Ethyl acetate has a lower polarity index (P 1 = 4.3) than methanol (P 1 = 6.6) [29], therefore ethyl acetate is more likely to extract compounds with lower polarity, whereas methanol will extract compounds with a greater polarity. Based on the polarity indexes of the solvents, isolates S21 and S4 were shown to produce both non-polar and polar bioactive compounds as the extracts prepared with both solvents were capable of inhibiting mycelial growth from B. cinerea cultures.…”

Preparation of Chiral Triacylglycerols, <i>sn</i>-POO and <i>sn</i>-OOP, via Lipase-mediated Acidolysis Reaction

“…Judging from the Snyder s polar parameter 19 value of 0.1, 2.7, and 5.1 for hexane, benzene, and acetone, respectively, these results indicate that polarity of reaction solvents affects the lipase activity for acidolysis reaction. Domingo et al reported that, in lipase-catalyzed aza-Michael addition reactions, the target compounds were successfully synthesized in a non-polar hexane medium, whereas aminolysis side reaction proceeded in polar solvents 20 . In addition, water-miscible acetone might cause denaturation of the lipase by removing its essential water molecules.…”
