The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in k Pa . The third column is the density of the liquid phase.
At the industrially used reaction temperature of 450 to 550 °C an optimum between the decomposition of ammonia into the starting materials and the effectiveness of the catalyst is achieved. [57] The formed ammonia is continuously removed from the system. The volume fraction of ammonia in the gas mixture is about 20%.
The sensitivity of the molecule to a broad range of excitations and the ease with which it can be observed in a number of regions has made ammonia one of the most important molecules for studies of molecular clouds. [174] The relative intensity of the ammonia lines can be used to measure the temperature of the emitting medium.
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...

The people in Donald Trump’s orbit are floating some dramatic ideas that would remake the way banks are regulated. There are lots of questions about whether any of the ideas will come to pass.
The UAE has a small Jewish community, thought to number thousands. Last year, the Gulf state opened its first-ever purpose built synagogue. Called the “Abrahamic Family House,” the interfaith ...
The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light. The diffusivity of the solvated electron in liquid ammonia can be determined using potential-step chronoamperometry. [6] Solvated electrons in ammonia are the anions of salts called electrides. Na + 6 NH 3 → [Na(NH 3) 6] + + e −
