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.
Claims12
A process for making an amine halide comprising:
- reacting substantially stoichiometric amounts of elemental halogen selected from the group consisting of CL, Br and I;
- a second compound selected from the group consisting of hydrazine, hydrazine hydrate, and compounds which generate hydrazine under the reaction conditions;
- and,
- a third compound selected from the group consisting of amines and salts thereof which generate the amine under the reaction conditions;
- in a reaction medium selected from the group consisting of water, alcohols, ethers and mixtures thereof.
