The phospha-Brook rearrangement of dialkyl 1-aryl-1-hydroxymethylphosphonates (HPs) to the corresponding benzyl phosphates (BPs) has been elaborated under solid-liquid phase transfer catalytic conditions. The best procedure involved the use of triethylbenzylammonium chloride as the catalyst and Cs2CO3 as the base in acetonitrile as the solvent at room temperature. The substrate dependence of the rearrangement has been studied, and the mechanism of the transformation under discussion was explored by quantum chemical calculations. The key intermediate is an oxaphosphirane. The one-pot version starting with the Pudovik reaction has also been developed. The conditions of this tandem transformation were the same, as those for the one-step HP→BP conversion.

Abstract This work reports influence of two different electrolytes, carbonate ester and ether electrolytes, on the sulfur redox reactions in room-temperature Na–S batteries. Two sulfur cathodes with different S loading ratio and status are investigated. A sulfur-rich composite with most sulfur dispersed on the surface of a carbon host can realize a high loading ratio (72% S). In contrast, a confined sulfur sample can encapsulate S into the pores of the carbon host with a low loading ratio (44% S). In carbonate ester electrolyte, only the sulfur trapped in porous structures is active via ‘solid–solid’ behavior during cycling. The S cathode with high surface sulfur shows poor reversible capacity because of the severe side reactions between the surface polysulfides and the carbonate ester solvents. To improve the capacity of the sulfur-rich cathode, ether electrolyte with NaNO3 additive is explored to realize a ‘solid–liquid’ sulfur redox process and confine the shuttle effect of the dissolved polysulfides. As a result, the sulfur-rich cathode achieved high reversible capacity (483 mAh g−1), corresponding to a specific energy of 362 Wh kg−1 after 200 cycles, shedding light on the use of ether electrolyte for high-loading sulfur cathode.

Nutmeg oleoresin microcapsule is the solid, liquid, and gas coating technology of the nutmeg fruit.  The purpose of this study was to know how mace nutmeg oleoresin microcapsules could preserve the broiler chicken meat at room temperature during 4 days of observation. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments with mace concentration of nutmeg microcapsules oleoresin (0, 50, 100, 150, and 200) ppm. The variables observed were water content, pH value, total microbes, and organoleptic properties (color, aroma, and texture). The results showed that mace nutmeg oleoresin microcapsules did not affect (p> 0.05)  water content and sensory properties of broiler chicken meat, but had a significant effect (p <0.05) on the pH value and total microbe at the same day of room temperature storage. Panel organoleptic test results on the level of preference for meat color, aroma, and texture of chicken meat were in the range score of 3 (somewhat like) to 4 (somewhat dislike). The treatments of nutmeg oleoresin did not affect (p> 0.05) on color, the aroma, and the texture of broiler chicken meat. This research shows that marinating using oleoresin microcapsules has not been effective as a preservative to broiler chicken meat at room temperature.

Bioinorganic complexes of nicotinic acid with trivalent antimony and bismuth are synthesized by solid-liquid reaction at room temperature. The formula of the complexes is Sb(C5H4NCOOH)2Cl3•H2O and Bi(C5H4NCOOH)2Cl3•H2O respectively. The crystal structure of the complex of nicotinic acid and Sb(III) belongs to triclinic system and that of nicotinic acid and Bi(III) belongs to monoclinic system. Thermal analysis can indicate the complex formation between antimony or bismuth ion and nicotinic acid.

The formation of different complexes in aqueous solutions is an important step in understanding the behavior of zinc chloride in water. The structure of concentrated ZnCl2solutions is governed by coordination competition of Cl−and H2O around Zn2+. According to the solid–liquid phase diagram, the title compounds were crystallized below room temperature. The structure of ZnCl2·2.5H2O contains Zn2+both in a tetrahedral coordination with Cl−and in an octahedral environment defined by five water molecules and one Cl−shared with the [ZnCl4]2−unit. Thus, these two different types of Zn2+cations form isolated units with composition [Zn2Cl4(H2O)5] (pentaaqua-μ-chlorido-trichloridodizinc). The trihydrate {hexaaquazinc tetrachloridozinc, [Zn(H2O)6][ZnCl4]}, consists of three different Zn2+cations, one of which is tetrahedrally coordinated by four Cl−anions. The two other Zn2+cations are each located on an inversion centre and are octahedrally surrounded by water molecules. The [ZnCl4] tetrahedra and [Zn(H2O)6] octahedra are arranged in alternating rows parallel to [001]. The structure of the 4.5-hydrate {hexaaquazinc tetrachloridozinc trihydrate, [Zn(H2O)6][ZnCl4]·3H2O}, consists of isolated octahedral [Zn(H2O)6] and tetrahedral [ZnCl4] units, as well as additional lattice water molecules. O—H...O hydrogen bonds between the water molecules as donor and ZnCl4tetrahedra and water molecules as acceptor groups leads to the formation of a three-dimensional network in each of the three structures.
