Usage

General Description

Formic acid is a colorless, pungent liquid that is commonly used in organic synthesis and as a preservative in livestock feed. It is also naturally produced by ants and other insects, and is used by some as a potent venom. Cobalt salt refers to a variety of compounds that contain the element cobalt and a salt-forming anion, such as chloride or sulfate. These salts are commonly used in the production of pigments, as catalysts in chemical reactions, and in the manufacture of vitamin B12. When combined, formic acid and cobalt salt can form a variety of cobalt formate compounds, which are used in applications such as the production of catalysts and as a hydrogenation reagent in organic chemistry.

Thermal dehydration of cobalt and zinc formate dihydrates by controlled-rate thermogravimetry (CRTG) and simultaneous X-ray diffractometry-differential scanning calorimetry (XRD-DSC)

The thermal dehydration study of the similar hydrated salts, cobalt and zinc formate dihydrates, have been carried out successfully by means of X-ray diffractometry-differential scanning calorimetry (XRD-DSC) and controlled-rate thermogravimetry (CRTG). X-ray diffraction analysis recorded simultaneously indicates that the resulting anhydrous product, Zn(HCO2)2, was crystalline, while Co(HCO2)2 was amorphous. The XRD-DSC data are proven to be invaluable in verifying the interpretation of overlapping processes in thermal events. In addition, these differences in the resulting anhydrous products can be explained from kinetic analysis results based on the CRTG data. The kinetic mechanism governing the dehydration of zinc formate dihydrate is a nucleation and growth process, while in the case of cobalt formate dihydrate a phase boundary controlled reaction is the governing mechanism.

Measurement of equilibrium water vapor pressures for the thermal dehydrations of some formate dihydrates by means of the transpiration method

The equilibrium water vapor pressures, PH2O for the thermal dehydrations of some formate dihydrates, M(HCO2)2·2H2O, where M is Mg, Mn, Co, Ni and Zn, were measured by means of the transpiration method using a laboratory-made apparatus. These hydrates have a monoclinic isomorphous crystal structure with a space group, P21/C. The thermodynamic data such as ΔG, ΔH and ΔS for the dehydration were derived from the PH2O and correlated to the crystal structures of these hydrates. Although the values of ΔH were expected to increase in the order of the hydrates of Mn2+-OH2 bond, they increased in the order of Mn2)2·2H2O and Zn(HCO2)2·2H2O seemed to be due to the relatively strong hydrogen bond between the water molecules and the formate ions. The values of ΔG obtained at 373 K, ΔG(373) showed a good correlation with the beginning temperatures of the dehydrations, Ti.

New complexes of Mn(II), Co(II), Ni(II) and Cu(II) with 2,2'- or 2,4'-bipyridine and formates (Synthesis, thermal and other properties)

New mixed-ligand complexes with empirical formulae: Mn(2-bpy) 1.5L2?2H2O, M(2-bpy)2L 2?3H2O (M(II)=Co, Cu), Ni(2-bpy)3L 2?4H2O and M(2,4'-bpy)2L 2?2H2O (where 2-bpy=2,2'-bipyridine, 2,4'-bpy=2,4'-bipyridine; L=HCOO- ) have been obtained in pure solid-state. The complexes were characterized by chemical and elemental analysis, IR and VIS spectroscopy, conductivity (in methanol and dimethylsulfoxide). The way of metal-ligand coordination discussed. The formate and 2,4'-bpy act as monodentate ligands and 2-bpy as chelate ligand. The new complexes with ligand isomerism were identified. During heating the complexes lose water molecules in one or two steps. Thermal decomposition after dehydration is multistage and yields corresponding metal oxides as final products. A coupled TG-MS system was used to analysis principal volatile thermal decomposition (or fragmentation) products of Ni(2,4'-bpy)2(HCOO) 2?2H2O under dynamic air or argon atmosphere.
