1.3 Synthetic Route

It is obtained by crystallization of gluconic acid and copper oxide.
It is obtained by crystallization of gluconate and copper salt.
It is obtained by crystallization of sodium gluconate and copper sulfate.
After electrolyzing glucose to gluconic acid, it is neutralized with copper carbonate and sorbitol.

It is obtained by the reaction of gluconic acid with copper oxide, or by the reaction of gluconate with copper salt, and then crystallization. It can also be made from copper phosphate neutralizing gluconic acid.
