PREPARATION OF SODIUM NITRATE FROM COMMON SALT AND AMMONIUM NITRATE BY DOUBLE DECOMPOSITION TRANSFORMATION
Abstract:
In order to find an economical way to prepare sodium nitrate studies have been carried out on the reciprocal system Na+-NH4+-Cl--NO3--H2O.Though the salt-pair of NaNO3-NH4Cl is a stable one,as the phase diagram shows, it is difficult to obtain pure NaNO3 and NH4Cl from it,for the solubilities of NaNO3 and NH4Cl vary with temperature almost in the same extent. A certain sort of optimum conditions has been approached at which the crystal of NaNO3 is more heavy with that of NH4Cl suspending in the solution, thus NaNO3 can be easily separated from NH4Cl.
