IUPAC-NIST solubility data series. 73. Metal and ammonium formate systems

This volume reviews the metal and ammonium formate solubility data published up to 1995. So far as the editors are aware, all the solubility data published during this period have been reviewed. Preference has been given to data published in numerical form. Data that appeared only in graphical form may not appear in this volume. In each section the metal atoms are arranged in the order (group) in which they appear in the Periodic Table. Metal atoms are arranged in the order (group) in which they appear in the Periodic Table. Metal formates are crystalline solids having some interesting chemical and physical properties. Several of these salts are important because they have nonlinear optical properties. Specific examples are: LiCHO2.H2O (3), NaCHO2 (4), Sr(CHO2)(2);, and Sr(CHO2)(2). 2H(2)O, Ba(CHO2)(2), formates of Sc, Y and the rare earth elements having the general formula Me(CHO2)(3). nH(2)O (where Me=Sc, Y, La, Ce, Pr, Nd, Sm...Lu) and some double salts and mixed salts such as NaCd(CHO2)(3), BaCd(CHO2)(4). 2H(2)O and Li0.9Na0.1CHO2. Some metal formates have useful electric or magnetic characteristics. Thus, Cu(CHO2)(2). 4H(2)O has ferroelectric properties, Cu(CHO2)(2) is ferromagnetic, Mn(CHO2)(2). 2H(2)O is antiferromagnetic, CuBa2(CHO2)(6). 4H(2)O is paramagnetic, and the formates of Ca, Cd, and Sr have elastic and thermoplastic properties. Bivalent metal formates could be used as precursors for the production of catalysts because they show excellent miscibility in the solid state, i.e., they form mixed crystals that dissociate at relatively low temperatures (about 300 degreesC) to form the respective oxides and mixed oxides. There are also additional smaller-scale uses of metal formates. The wide interest in the applications and uses of metal formates will lead to an interest in seeking methods for the preparation of these materials. Solubility data for the metal formates will be helpful in devising the methods of preparation. Therefore, this volume has been prepared to present and evaluate solubility data for the binary, ternary and multicomponent systems containing metal formates in aqueous and in nonaqueous solutions.
