Technology Process of Nitrogen

There total 1392 articles about Nitrogen 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: 80.0%

potassium nitrite (7758-09-0) + hydroxyammonium sulfate → nitrogen (7727-37-9) + dinitrogen monoxide (10024-97-2)

Guidance literature:

In not given; in acidic soln. from equimolar amounts of components; mole ratio N2O : N2 depends on the mole ratio of nitrite : hydrazonium salt;;

Reference yield: 20.0%

water (7732-18-5) + nitrogen(II) oxide (10102-43-9) → nitrogen (7727-37-9) + ammonia (7664-41-7) + dinitrogen monoxide (10024-97-2)

Guidance literature:

With CO; In gaseous matrix; react. carried out at 573 K by use of conventional flow system with fixed bed of catalyst (Pt-Al2O3) under gas composition NO, CO 3%, H2O 1.7%,He 92.3% for 150 min; gas chromy. and MS anal.;
