Solid–Liquid Equilibrium in the Ternary MgBr₂–MgSO₄–H₂O System at 348.15 K and Its Application

The solid–liquid equilibrium of the ternary MgBr2–MgSO4–H2O system at 348.15 K was explored by using the isothermal equilibrium method, intending to realize the comprehensive utilization of the basic magnesium bromide (MgBrOH) waste residue produced in maltol production. It was observed that the phase diagram was composed of four single-salt crystallization regions, four univariate solubility curves, three invariant points saturated with MgSO4·6H2O + MgSO4·4H2O, MgSO4·4H2O + MgSO4·H2O, and MgSO4·H2O + MgBr2·6H2O, respectively, and three corresponding cocrystallization zones. Neither double salts nor a solid solution appears. The ion-interaction parameters at 348.15 K were determined using the Pitzer model, which were proven effective on this system. The calculated and experimental solubilities are coincident essentially. Based on the obtained phase diagram, a new technological process for the extraction of MgSO4 and MgBr2 from MgBrOH was proposed, and the purity of MgBr2 product was up to 99.65%. The MgBrOH waste residue produced from maltol production would achieve further development and create more benefits

Characteristics of the complete chloroplast genome of <i>Swertia divaricata</i> Harry Sm. (Gentianaceae) and its phylogenetic inference

Swertia divaricata Harry Sm., 1965, (Gentianaceae) is a perennial herb endemic to Northwest Yunnan, China, belonging to the species-rich genus Swertia. It possesses unique morphological features but its systematic position remains uncertain. To determine its phylogenetic placement, the complete plastid genome of S. divaricata was assembled utilizing high-throughput sequencing data. The genome is circular, spanning 152,073 bp, and comprises a large single-copy (LSC) region of 82,470 bp, a small single-copy (SSC) region of 18,153 bp, and two inverted repeats (IR) regions, each 25,725 bp. A total of 130 genes were annotated, including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The plastome of S. divaricata exhibits a structure and gene composition highly similar to those of other Swertia plastomes. Phylogenetic analysis indicated that S. divaricata is closely related to S. erythrosticta, sister to a subclade comprising species from sections Swertia and Apterae. The plastome sequence described herein constitutes a valuable contribution to phylogenetic and evolutionary research on Swertia.</p

Asymmetric Synthesis of 3,4-Diaminochroman-2-ones Promoted by Guanidine and Bisguanidium Salt

A highly enantioselective synthesis of 3,4-diaminochroman-2-ones has been realized via the domino reaction of o-hydroxy aromatic aldimines and azlactones. Notably, a cis-product was obtained as the major product by the use of guanidine 2a whereas a trans-product was the major product with bisguanidium salt 3•HBArF4. In two cases, various substituted 3,4-dihydrocoumarins were obtained with high yields (up to 99%) as well as excellent enantioselectivities (up to 99% ee) and diastereoselectivities (up to >99:1 cis:trans and 98:2 trans:cis, respectively) under mild reaction conditions
