《Study of Liquid-Liquid Equilibrium of Aqueous Two-Phase Systems Based on Ethyl Lactate and Partitioning of Rutin and Quercetin》 was written by Requejo, Patricia F.; Velho, Pedro; Gomez, Elena; Macedo, Eugenia A.. Application of 6381-59-5 And the article was included in Industrial & Engineering Chemistry Research in 2020. The article conveys some information:
Two Et lactate (EL)-based aqueous two-phase systems (ATPSs) were studied at T = 298.15 K and atm. pressure. Sodium tartrate and potassium sodium tartrate organic salts have been used to form biphasic systems. To assess the phase splitting, binodal curves and tie-lines were obtained exptl. by the cloud point method and a technique, which consist of the d. and refractive index, resp. Binodal curves were fitted with the Merchuk equation obtaining a good fit. Moreover, modeling with the universal quasichem. thermodn. equation was carried out to accurately represent the two-biphasic systems. Furthermore, exptl. binodal curves obtained in this work and literature results for the same systems and for systems with EL and other salts were analyzed regarding their similarity. Finally, the application of the adopted ATPS in the partitioning of two flavonoids, rutin and quercetin, was studied in terms of the partition coefficients and the percentage of extraction Rutin and quercetin showed better affinity to the EL-rich phase, evidencing that the use of the proposed ATPS may be a successful technique in the biotechnol. industry for the separation of each flavonoid. In the experiment, the researchers used many compounds, for example, Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Application of 6381-59-5)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Application of 6381-59-5 Potassium sodium tartrate tetrahydrate has been used in the preparation of Lowry reagent for the determination of microsomal protein concentration in rat hepatic microsomes by Lowry method.
