text: Traditionally, oxalic acid has been extracted from natural products by treating them with an alkaline solution, followed by crystallization of the acid.
text: K. Analyzing the distribution coefficients and selectivities, we conclude that TBP appears to be a good solvent for extraction purposes when oxalic acid needs to be extracted from its aqueous solutions, because the distribution coefficients are always higher than 1 and the selectivities are sufficiently high (see Table 1).
