Abstract:
1. A method for preparing an organic zinc salt, comprising: a) mixing an aqueous zinc ammonia carbonate complex solution with one or more organic acids and/or soluble organic acid salts to form an aqueous mixture; b) agitating, and optionally heating, the aqueous mixture to at least partially remove ammonia and carbon dioxide from the aqueous mixture, thereby forming said organic zinc salt in water; c) optionally, cooling the organic zinc salt in the water to a temperature of from about 5° C. to 30° C.; d) filtering the organic zinc salt to isolate said organic zinc salt; e) optionally, washing the isolated organic zinc salt; f) drying the isolated organic zinc salt; and g) optionally, milling the isolated organic zinc alt.
