Цель изобретени - получение хлора, углекислого натри и нитрата аммони -натри , а также более полное использование сырь .The purpose of the invention is to obtain chlorine, sodium carbonate and ammonium nitrate nitrate, as well as to make fuller use of the raw material.
По предлагаемому способу аммонизацию и карбонизацию азотнокислого раствора ведут до содержани нитратов аммони и натри в смеси более 70%, а общего азота более 30%. Непрореагировавшие хлорид-ионы удал ют из раствора посредством отдувки окисью азота .According to the proposed method, ammonization and carbonization of the nitric acid solution are carried out to a content of ammonium and sodium nitrates in a mixture of more than 70%, and total nitrogen more than 30%. Unreacted chloride ions are removed from the solution by stripping with nitrous oxide.
Способ осуществл ют следующим образом. Хлорид натри окисл ют азотной кислотой, раствор, содержащий нитрат натри и избыток азотной кислоты, нейтрализуют газообразным аммиаком до образовани нитрата аммони . Раствор нитратов аммони и натри карбонизуют двуокисью углерода до образовани выпадающего в осадок бикарбоната натри и бикарбоната аммони .The method is carried out as follows. Sodium chloride is oxidized with nitric acid, the solution containing sodium nitrate and excess nitric acid is neutralized with ammonia gas to form ammonium nitrate. The ammonium and sodium nitrate solution is carbonized with carbon dioxide to form precipitated sodium bicarbonate and ammonium bicarbonate.
Бикарбонат натри выдел ют из раствора фильтрацией и кальцинируют до получени углекислого натри . После удалени бикарбоната иатри раствор нагревают до разложени бикарбоната аммони на аммиак, двуокись углерода и воду. Оставшийс раствор концентрируют путем испарени и выдел ют из него кристаллы нитрата аммони -натри .Sodium bicarbonate is separated from the solution by filtration and calcined to obtain sodium carbonate. After the bicarbonate is removed, the solution is heated until ammonium bicarbonate is decomposed into ammonia, carbon dioxide and water. The remaining solution is concentrated by evaporation and the crystals of ammonium nitrate ammonium nitrate are separated from it.

Пример. 12,8 моль хлорида натри окисл ют 70%-ной азотной кислотой до получени раствора, содержащего57,88% NaNOs, 10,72% HNOs, 31,40% НоО. Раствор нейтрализуют аммиаком до получени 12,8 моль NaNOs, 3,2 моль NH4N03, 10,8 моль ЫНзИ воды. Раствор карбонизуют двуокисью углерода до образовани и осаждени 9,6 моль NaHCOs. Состав раствора: 3,2 моль NaNOs, 12,8 моль КН4НОз,Example. 12.8 moles of sodium chloride are oxidized with 70% nitric acid to form a solution containing 57.88% NaNOs, 10.72% HNOs, 31.40% Ho. The solution is neutralized with ammonia to obtain 12.8 mol of NaNOs, 3.2 mol of NH4N03, 10.8 mol of Na2NI of water. The solution is carbonized with carbon dioxide to form and precipitate 9.6 mol of NaHCOs. The composition of the solution: 3.2 mol NaNOs, 12.8 mol KN4Noz,
1,2 моль и вода. Раствор нагревают дл удалени наров NHsCOa и НзО до содержани в остаточном растворе 3,2 моль NaNOa, 12,8 моль NH4NO3 и воды. После испарени воды иолучают ннтрат аммони -натри с содержанием 79,46% нитрата аммони ,.1.2 mol and water. The solution is heated to remove NHsCOa and HzO to form a residual solution of 3.2 moles of NaNOa, 12.8 moles of NH4NO3 and water. After evaporation of water, ammonium nitrate with a content of 79.46% ammonium nitrate is obtained.
