Purification of the acid was increased, with some loss in extraction of P2O5, by partial ammoniation to a mole ratio NH3:H3PO4 of 0.1, with which 70% of the P2O5 was extracted with only 20% of the metallic impurities. solvents were monitored with charcoal tubes. hours. The carboxyl groups are not in the same plane as the methylene groups. Carboxylic acids donate hydrogen ions if a base is present to accept them. With partial ammoniation acetone extracted 85% of the P2O5 and only 20% of the metallic impurities, and the acetone was readily recovered by distillation. Each solvent has a major component in bio-oil products. The PLA films immersed in organic solvent became cloudy and showed no changes in chemical structure.

In addition, the solubility data of glutaric acid in five mixtures (cyclohexanone+cyclohexanol) could be predicted with the NRTL equation utilizing the parameters of the binary systems. The hydrogen bonding solubility parameter accurately reflects the solubility of PLA films using HSP but it depends on hydrogen bonding, as well as dispersion and polar parameters. The results show that solubilities of AA and SA in acetone or n-butanol increased with increasing mass fraction of GA in the mixed solvent GA and acetone (or n-butanol) at the same temperature. – P. 18–20.
