STUDY OF THE SOLUBILITY ISOTERM OF MANGANESE SULFATE - MONOETHANOLAMINE - WATER

Abstract

Solubility isotherm of the system manganese sulfate - monoethanolamine - water at 10ºС consists of two branches of crystallization of the initial components. The first branch corresponds to crystallization in the solid phase of manganese sulfate penta-water, and the second corresponds to the new compound composition: NH2C2H4OH -MnSO4- 3H2O. The new compound was isolated in crystalline form and identified by methods of chemical, graphic and X-ray phase analysis. Preliminary agrochemical tests have shown that it increases the yield of cotton and grain crops by 3-7 c/ha and improves the quality of products.
