Abstract
The invention relates to a method for producing aprotic solutions that contain zinc bromide and lithium bromide, the reaction of the reactants to the product being carried out as a one-pot reaction.
Claims19
A method for producing an aprotic solution containing zinc bromide and lithium bromide, the method comprising:
- dispersing starting materials in an aprotic solvent, wherein the starting materials comprise (i) zinc oxide or zinc carbonate, and (ii) lithium carbonate or lithium hydroxide;
- reacting the starting materials dispersed in the aprotic solvent with hydrobromic acid to form a reaction mixture;
- and
- removing water from the reaction mixture to form a product solution
- with a residual water content <2500 ppm;
- and
- separating the product solution from unreacted starting materials.

A method for producing an aprotic solution containing zinc bromide and lithium bromide, the method comprising:
- mixing aqueous solutions of zinc bromide and lithium bromide in a stoichiometric ratio, and
- adding an aprotic solvent thereto in volume sufficient to remove water which is present to form the aprotic solution with a residual water content <2500 ppm.
A method for producing an aprotic solution containing zinc bromide and lithium bromide, the method comprising
- dispersing starting materials in an aprotic solvent, wherein the starting materials comprise a mixture of metallic zinc and metallic lithium;
- reacting the starting materials dispersed in the aprotic solvent with hydrogen bromide or elemental bromine to form a product solution;
- and
- separating the product solution from unreacted starting materials.
