Webb6 juni 2024 · The experimental pKa value, 20.7, was determined through UV/Vis titrations. Its solubility was measured in methanol-modified supercritical CO2 (mole fraction, 3.23×10−4, cloud points 40–80 °C) and it was shown to be less soluble than 5-hydroxymethylfurfural (5-HMF). WebbIt is a weak acid with pKa repor - ted in different sources to be between 4.52 and 5.314,15. ALA is sparingly soluble in water16, but soluble in organic solvents16,17. It has two enan- tiomeric forms, S and R. The R isomeric form is present naturally, while the S isomer is prepared through chemical processes18. Various studies19,20
