Technology Process of Potassium nitrite(III)

There total 72 articles about Potassium nitrite(III) 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: 91.0%

potassium chloride + sodium nitrite (7632-00-0) → potassium nitrite (7758-09-0)

Guidance literature:

In water; 88-97 % KNO2 content after evapn. to dryness and recrystn.; NaCl removed by pptn. by AgNO2 or AgNO3;

Reference yield:

nitrogen(II) oxide (10102-43-9) → potassium nitrite (7758-09-0) + nitrogen (7727-37-9) + dinitrogen monoxide (10024-97-2)
