Research Of Mutual Effect Of Components In Water Systems Including Calcium, Magnesium Nitrates And Monoethanolammonium Acetate

Abstract

This Article Presents The Results Of A Study Of The Mutual Influence Of Components In aqueous systems, including calcium and magnesium nitrates and a physiologically active substance, monoethanolammonium acetate. Their polythermal solubility diagrams are constructed. It has been established that the

Ca (NO3) 2-CH3COOH ? NH2C2H4OH-H2O system belongs to a complex type. Its solubility diagram revealed crystallization fields: ice, tetra-, tri- and dihydrous calcium nitrate, acetic acid, monoethanolammonium acetate and, as a new phase, the compound Ca (NO3) 2 ? NH2C2H4OH. The formation of Ca (NO3) 2 ? NH2C2H4OH in this system was confirmed by the methods of chemical and X-ray phase analysis.

The solubility polytherm of the Mg (NO3) 2-??3???? ? NH2C2H4OH-?2? system is characterized by the presence of crystallization fields of the initial components on its diagram. That is, this system is of a simple eutonic type. The results obtained serve as a scientific basis for obtaining a liquid fertilizer of complex action based on the product of nitric acid decomposition of dolomite and a physiologically active substance
