Quality Control of Picolinic acidIn 2019 ,《Thermochemistry of the Acid-Base Interactions in Aqueous Solutions of Isonicotinic and Picolinic Acids》 was published in Russian Journal of General Chemistry. The article was written by Lytkin, A. I.; Badelin, V. G.; Krutova, O. N.; Tyunina, E. Yu.; Krutov, P. D.. The article contains the following contents:
The calorimetric method was employed to measure the heat effects of the interaction of isonicotinic and picolinic acids with HNO3 in aqueous solutions over different pH ranges at 298.15 K and ionic strengths of 0.5, 1.0, and 1.5 against potassium nitrate. The heat effects of stepwise dissociation of the acids were determined The standard thermodn. characteristics (ΔrH°, ΔrG°, ΔrS°, ΔCp°) of the acid-base reactions in aqueous solutions of isonicotinic and picolinic acids were calculated The results came from multiple reactions, including the reaction of Picolinic acid(cas: 98-98-6Quality Control of Picolinic acid)
Picolinic acid(cas: 98-98-6) is used as a chelate for alkaline earth metals. Used to prepare picolinato ligated transition metal complexes. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.Quality Control of Picolinic acid
