TL;DR: In this paper, a method for the production of zinc oxalate dihydrate was proposed, which includes preparation of reaction solution containing zinc (II) and oxalates, crystallization of target product, separation of sediment from solution and drying the sediment.
Abstract: FIELD: updating of process of production of zinc oxalate dihydrate. ^ SUBSTANCE: product obtained by this method may be used as pigment for production of catalysts of synthesis of inorganic and organic substances, manufacture of ceramic articles and production of oxide and other compounds of zinc. Proposed method includes preparation of reaction solution containing zinc (II) and oxalate, crystallization of target product, separation of sediment from solution and drying the sediment; reaction solution is prepared by mixing the solution of zinc plating process and oxalate-containing reagent; use is made of used solution of zinc plating process and reaction solution containing zinc (II) and oxalate at mole ratio of 1.0: (0.8-3.0) is prepared. ^ EFFECT: low cost of process at retained purity; possibility of utilization of toxic waste of zinc plating process. ^ 12 cl, 7 ex

TL;DR: The static membrane method was used to study the temperature dependences of equilibrium guest vapor pressure over inclusion compounds of two coordination polymers with chlorobenzene, [M(bipy)(DBM)2] · 2C6H5Cl.
Abstract: The static membrane method was used to study the temperature dependences of equilibrium guest vapor pressure over inclusion compounds of two coordination polymers with chlorobenzene, [M(bipy)(DBM)2] · 2C6H5Cl, where M = M(II) = Zn and Ni, bipy = 4,4′-dipyridyl, and DBM = C6H5COCHCOC6H 5 − is the dibenzoylmethanate anion. The data obtained were used to calculate the thermodynamic parameters of dissociation of these compounds. The regions of their existence and the stoichiometry and character of phase transitions were determined by thermogravimetric and differential thermal analyses.

TL;DR: The obtained results testify that essential role is not played by separate fragments (L-ligand and anions), but by molecules of zinc complexes as a whole, and that the character of interaction of zinc complex is changed depending on the enzyme tested and its strain-producer.
Abstract: The influence of a number of coordinative compounds of zinc with N-substituted thiocarbamoil-N'-pentamethylensulfenamides on activity of elastase, alpha-L-rhamnosidase and alpha-galactosidases evidence for a possibility of their usage as stimulators or inhibitors of enzymes tested have been studied. It was shown that all the compounds in concentration of 0.1 and 0.01% inhibited by 90-100% Bacillus thuringiensis 27-88Els+ elastase activity. [Zn(L2)Br2], [Zn(L1)(NCS)2] and [Zn(L3)(NCS)2] at 20 h exposition activated Cryptococcus albidus 1001 alpha-L-rhamnosidase activity. The rest of compounds influenced it on the control level or inhibited it by 7-23%. The obtained results testify that essential role is not played by separate fragments (L-ligand and anions), but by molecules of zinc complexes as a whole. All the studied complexes, exept for [Zn(L3)(NCS)2], induced alpha-L-rhamnosidase activity of Eupenicillium erubescens 248 (7 to 60%). All zinc compounds (concentration 0.01%, exposition time - 60 min) influenced at the control level Aspergillus niger and Cladosporium cladosporioides alpha-galactosidases activity, however inhibited (up to 20%) activity of Penicillium canescens alpha-galactosidase. The increasing of exposition time of the compounds tested with enzymes up to 20 h testify to selective action of separate compounds on enzymes tested. The data obtained prove, that the character of interaction of zinc complexes is changed depending on the enzyme tested and its strain-producer.

TL;DR: In this article, a luminescent compound based on zinc, gallium and oxygen was described, whose preparation process and its utilization as luminophore was described. And the compound was characterized in that it has a spinelle structure and an atomic ratio Ga/Zn of at least 25 and an X ray spectrum within which the position of the spectral lines on the 2 theta axis is situated between the line positions of the compositions Ga2O3 and ZnGa2O4.
Abstract: The invention relates to a compound, more particularly a luminescent compound, based on zinc, gallium and oxygen, its preparation process and its utilization as luminophore The compound is characterized in that it has a spinelle structure and in that it has an atomic ratio Ga/Zn of at least 25 and an X ray spectrum within which the position of the spectral lines on the 2 theta axis is situated between the line positions of the compositions Ga2O3 and ZnGa2O4 Said compound is obtained by preparing an homogeneous mixture at the atomic scale of the compounds of zinc, gallium and optionally the dopant; by proceeding to a first calcination with the air of the mixture and by carrying out a second calcination of the product obtained from the first calcination in a reducing atmosphere
