Technology Process of Sodium metaphosphate

There total 13 articles about Sodium metaphosphate 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:

sodium dihydrogenphosphate (10049-21-5) → sodium hypophosphate (10361-03-2)

Guidance literature:

In neat (no solvent); repeated fusion of NaH2PO4 and cooling the latter up to 500°C in the course of 2 d, removing of residual water;

Reference yield:

3Na(1+)*NH4(1+)*P4O12(4-)*10H2O=Na3NH4P4O12*10H2O → sodium hypophosphate (10361-03-2) + ammonia (7664-41-7)

Guidance literature:

In neat (no solvent); heating for a long period;

Reference yield:

Na(1+)*3NH4(1+)*P4O12(4-)*12H2O=Na(NH4)3P4O12*12H2O → sodium hypophosphate (10361-03-2) + ammonia (7664-41-7)

Guidance literature:

In neat (no solvent); prolonged heating;
