Title: Improvement in production of alkali and alkaline earth metal nitrates
IPC: C01F11/36
Filed: 1934-08-13
Abstract: Alkali and alkaline-earth metal nitrates for instance, sodium, potassium, and calcium nitrates are obtained by heating to temperatures above about 50 DEG  C., a reaction mixture containing nitric acid and the corresponding chloride, the original nitric acid concentration being above about 40 per cent HNO3 and the heating being continued until the nitric acid content of the mixture is not greater than that corresponding to a 7 normal solution.  Preferably a gas having a lower partial pressure of the gaseous products of the reaction than the heated reaction mixture itself is passed into direct contact with the reaction mixture, as by passing thereinto steam obtained by boiling the resulting nitrate solution.  Reaction may take place in a bubbling tower, or preferably in a series of vessels maintained at progressively higher temperatures up to boiling, the steam and gases evolved at the higher temperatures being contacted with the reaction mixture at the lower temperatures. Insufficient sodium chloride to react with all the nitric acid but more than the nitric acid can dissolve is preferably used, the reaction gases then comprising a mixture of nitrosyl chloride and chlorine.  The nitrate solution obtained is neutralized and concentrated to separate solid nitrate, and mother liquor or some solid nitrate may be returned to the reaction mixture or to the nitrate solution when this is being boiled.  Reaction may, if desired, be effected at superatmospheric pressure, and take place in apparatus having metal surfaces of a chrome-iron alloy containing 18--28 per cent of chromium.  Mother liquor containing nitrate and residual undecomposed chloride may be evaporated at alternately lower and higher pressures, say at \ba1/10\be of an atmosphere and then at atmospheric pressure, to crystallize out the nitrate and chloride respectively.
