Polythermal Solubility of Ternary System Sodium Chlorate–Triethanolammonium Nitrate–Water and Rheological Properties at 25°C
Abstract
The solubility of the NaClO3–HNO3·N(C2H4OH)3–H2O ternary system has been determined in the temperature range from –48.2 to 70.0°C by the visual polythermal method. Its phase diagram delimits the crystallization fields of ice, sodium chlorate, and triethanolammonium nitrate. The physicochemical and rheological properties of the [45%NaClO3 + 55%H2O]–HNO3·N(C2H4OH)3 section have been studied at isothermal temperature (25°C) in accordance with the change in the composition of the solution. Based on the obtained results, a “composition–properties” diagram of the [45%NaClO3 + 55%H2O]–HNO3·N(C2H4OH)3 section has been constructed. The research results show that the NaClO3-HNO3·N(C2H4OH)3–H2O system belongs to the simple eutonic type and no new chemical compounds are formed in it.
