Abstract:

A process for making halogen salts which comprises reacting elemental halogen, hydrazine or a hydrazine compound, and a compound selected from the oxides and hydroxides of alkali metals, alkaline earth metals, Zn, Bi, Sn(II,IV), and Mn(II), the carbonates and bicarbonates of the alkali metals, alkaline earth metals, Sc, Y, Ti(IV), Zr, Hf, V(IV), Nb, Ta, Mn(II), Fe(II), Co(II), Ni, Cu(I), Ag, Zn, Cd, Hg(II), Al, Ga(III), Tl(III), Sn(II,IV), Pb(II) and Bi and the hydrates thereof, ammonia and ammonium compounds, such as ammonium carbonate, amines such as ethylenediamine, in the presence of a solvent medium selected from water, alcohols, ethers, and mixtures thereof. Thus, lithium carbonate, hydrazine, and elemental iodine react in water to produce lithium iodide which can be isolated from the water solution by evaporation.
