Dilmurod A. Ergashev , Shokhida SH. Khamdamova
Abstract
Solubility and interaction of components in the systems calcium chlorate - monoethanolamine-water, calcium chlorate - diethanolamine-water and calcium chlorate - triethanolamine-water have been studied by visualpolythermal method over a wide range of temperatures and concentrations. The phase diagram delineates the crystallization fields of ice, Ca(ClO3)2-6H2O, Ca(ClO3)2-4H2O, Ca(ClO3)2-2H2O, NH2CH2CH2OH, NH2CH2CH2OH-H2O,NH2CH2CH2OH-2H2O, NH(C2H4OH)2, N(C2H4OH)3 and new compounds of the compositions Ca(OH)2, Ca(ClO3)2-
NH(C2H4OH)2 and Ca(ClO3)2∙N(C2H4OH)3. The formation of Ca(OH)2, Ca(ClO3)2-NH(C2H4OH)2 and Ca(ClO3)2∙N(C2H4OH)3 was confirmed by chemical, thermogravimetric and X-ray phase analysis.
