Nanoparticles of zinc compounds obtained by thermooxidative degradation

Abstract: Nanocrystalline zinc compounds were obtained by thermooxidative degradation of zinc complexes. There are presented the conditions of synthesis and results in the characterisation (chemical analysis, thermal analysis) for two complex compounds of zinc: [Zn(phen)(S 2 O 3 )(H 2 O)]·2H 2 O and [Zn(phen) 2 (H 2 O) 2 ][Zn(phen)(S 2 O 3 ) 2 ]·4H 2 O. On the basis of transmission electron microscopy (TEM) the complex sulfide and zinc oxide (prepared by controlled thermal decomposition of these compounds) may be included in the nanomaterials category.

Method of production of zinc oxalate dihydrate

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
