Filed: 1962-02-05
Abstract: Chlorine and alkali metal nitrates are produced by treating a chloride of the alkali metal with at least four times its chemical equivalent of nitric acid of at least 60% concentration and at a pressure of from 12 to 30 absolute atmospheres and a temperature of from 100 DEG  to 175 DEG  C.  At least 85% by volume of the resulting gas is chlorine.  The Cl2 gas is separated from the liquid phase and the NOCl oxidized in the solution with O2 gas to obtain Cl2 gas and a solution of nitrate.  At least four times the stoichiometric quantity of HNO3 according to equation 3NaCl+4HNO3+O2--> 3NaNO3+Cl2+NOCl+2H2O is used.  The process is performed in an autoclave of Ti or Ta. The pressures used are preferably higher than those at which separation occurs between the Cl2 in the gas phase and the NOCl which passes into the liquid phase.  The solution is passed to another reactor at 150-175 DEG  C. at which temperatures the highest partial pressures of Cl2 must not exceed 8 and 12 absolute atmospheres respectively, O2 gas is added in amount 0.75 moles for each mole of NOCl.  From the final liquid, the nitrate is separated by cooling and the dilute acid is concentrated and recycled.
