dc.description | Objective. The article introduces a predetermination of the possibility of a reaction and therefore of the salt composition of the final products which, due to the complexity of the original and final products, is extremely difficult. Therefore, the reaction of tricalcyphosphate, calcium carbonate, magnesium, iron oxides and aluminium, i.e. those which are possible during the production of phosphorus sulfur-containing fertilizers, was analysed. Methods. Thermodynamic analysis makes it possible to predetermine the possibility of a reaction and therefore the salt composition of the final products, which are extremely complex due to the complexity of the original and final products.Therefore, the reaction of tricalcyphosphate, calcium carbonate, magnesium, iron oxides and aluminium, i.e. those which are possible during the production of phosphorus sulfur-containing fertilizers, was analysed. For each reaction we found the isobarn-isothermic potential and judged the possibility of a reaction (negative value G).Thermodynamic calculations of possibilities of formation of phosphates and sulphates of calcium, magnesium, iron, aluminium in process of production of sulfur-containing nitrogen-phosphorus fertilizers were carried out according to simplified formula ∆G=∆Н-T∆S Thermal capacity excluded. Results. The phosphates of the Central Kyzylkum differ substantially from the phosphate Karatau in chemical composition and therefore the main contribution to the thermal effect of the interaction of phosphate with phosphate and sulfuric acids are the processes of interaction with tricalcyphosphate and calcium carbonate. Conclusion. 96% the thermal effect of the interaction of phosphate CK is the interaction of tricalcyphosphate and calcium carbonate with phosphoric acid and 95,4% with sulphuric acid. The heat effects of the other components do not exceed 4-4,6%. | en-US |
