Technology Process of Sodium rhodizonate

There total 2 articles about Sodium rhodizonate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

ammonia (7664-41-7) + sodium (7440-23-5) → ammonium glycolate (35249-89-9) + diammonium rhodizonate + glycolamide (598-42-5) + sodium glycolate (25289-18-3,105938-46-3,2836-32-0) + sodium rhodizonate dibasic (523-21-7)

Guidance literature:

With carbon monoxide; ammonium chloride; In ammonia; adding NH4Cl before evapn. of NH3;

Reference yield:

rhodizonic acid (118-76-3) + sodium hydroxide (1310-73-2) → sodium rhodizonate dibasic (523-21-7)

Guidance literature:

In water; for 12h;
