Equation of stateThermophysical propertiesIn this study, three different equations of state (EoS) for the ammonia/water mixture are compared withexperimental data in order to find the EoS which best reproduces the measured data in the temperaturerange-30 °C≤≤200 °C and pressure range 1 bar...
Equation of state and electrical conductivity of "synthetic Uranus," a mixture of water, ammonia, and isopropanol, at shock pressure up to 200 GPa (2 Mbar) Equation-of-state, temperature, and electrical-conductivity data were measured for a solution of water, ammonia, and isopropanol at shock...
calculations predict that the catalytic effect of single ammonia and water molecule on OH + CH3OH reaction has no effect under tropospheric conditions because the dominated ammonia and water-assisted reaction depends on ammonia and water concentration, respectively. As a result, the total effective...
2) ammonia-water mixtures 氨-水混合工质 1. Based on the first law of thermodynamics and the properties of ammonia-water mixtures estimated by Peng-Robinson equation of state, a thermodynamic analysis of a representative Kalina cycle - the stair distillation cycle was presented. 编制了氨-水...
An equation of state for ammonia-water mixtures is presented. Separate equations of state for liquid and gas phases are provided for pure ammonia and pure water. In the gas phase, the mixture is assumed to behave as an ideal solution, while in the liquid phase, the Gibbs excess energy is...
Extensive new data on the phase behavior of the ammonia-water binary system were recently obtained by us in a comprehensive experimental study. These new data were correlated using a number of recent proposals for modifying binary mixing rules in equations of state. The Peng-Robinson equation was...

Ammonia (NH3) is a gas that readily dissolves in water and behaves as a base. The ammonia equilibrium is describe with the equation NH3 + H2O = NH4(+) + OH(-). Formally, the acidity of the solution is expressed as pH. This is the logarithm of the concentration of hydrogen ions (pro...
You can see from the reaction equation, also can lower the added value of ammonium, and the degree is about 0.9 (N/P) reacts with ammonia gas generated, neutralization degree is about 1.6 (N/P) ammonium phosphate (because it is an intermediate, ammonium and diammonium so called ammonium ...
Vapor−liquid equilibria of ammonia + water + potassium hydroxide and ammonia + water + sodium hydroxide systems were measured by a static method from (293.15 to 353.15) K. The experimental vapor pressure data have been correlated with temperature and mass percent concentration using an analytical...
