Product name:D-Gluconic acid copper(II) salt
CAS:527-09-3
Molecular Formula:C12H22CuO14
Formula Weight:453.84
Specification:25g
Description:D-gluconic acid copper(II) salt is a light blue to blue-green crystal or fine powder, odorless, highly soluble in water and extremely insoluble in ethanol.
D-gluconic acid copper(II) salt is obtained by reacting Gluconic acid with copper oxide, or Gluconic acid with copper salt, and then crystallizing. It can also be made from copper phosphate and gluconic acid.
The d-gluconic acid copper(II) salt was accurately weighed and dissolved in 100ml water in a 250ml conical flask. 2ml glacial acetic acid and 5g potassium iodide were added, mixed and titrated with 0.1mol/L sodium thiosulfate to a pale yellow. Add 2g ammonium thiocyanate, mix well, add 3ml starch test solution (ts-235) and continue titration to the milky end point. Sodium thiosulfate was equal to 45.38mg of d-gluconic acid copper(II) salt per Ml0.1mol/L.
D-gluconic acid copper(II) salt is used as a nutritional supplement. For strengthening copper in milk substitute, the content of copper in milk substitute shall not exceed 0.6mg per liter.
