AI Thread Summary
The discussion centers on the feasibility and safety of storing anhydrous NH3NO4 (ammonium nitrate) in sealed containers for use in a temporary refrigeration device within a hot environment, such as a closed car. Key considerations include the maximum storage temperature of 170 degrees F and the minimum of -30 degrees F. The importance of consulting the Material Safety Data Sheet (MSDS) for NH3NO4 is emphasized for understanding safe storage practices. The potential risks associated with storing the chemical in dry, sealed containers are highlighted, raising concerns about safety in high-temperature conditions. The idea of keeping the chemical in solution form is suggested as a possible alternative to mitigate risks.

Hello, I'm thinking about creating a temporary refrigeration device for cooling items in a hot enclosure (i.e closed car in the sun), and I was thinking about using on-demand NH3NO4 as the cooling agent. I understand how the reaction works and the implications of using the chemical, but I'm more thinking about storing the chemical in a warm environment.

So here's the question specifically: would anhydrous NH3NO4 be dangerous to store in dry, sealed containers of, say, 50-500g a piece? We'll say the absolute maximum temperature of the car will be 170 degrees F and the minimum, -30F.

Your first stop should be to look at the MSDS for storage of any chemicals.

Keep it as a solution maybe?
 
Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'
I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
I'm making poor man's nitric acid to refine silver from scrap. I would like to waste as little as possible. I've noticed that about half the acid is destroyed oxidizing the metals, and I'd like to reduce that if possible. One reference mentioned that I lose only one in four in a "dilute solution" instead of half. How dilute must it be to allow the NO2 to disproportionate so that half of it will redissolve and become nitric acid again?
Engineers slash iridium use in electrolyzer catalyst by 80%, boosting path to affordable green hydrogen https://news.rice.edu/news/2025/engineers-slash-iridium-use-electrolyzer-catalyst-80-boosting-path-affordable-green Ruthenium is also fairly expensive (a year ago it was about $490/ troy oz, but has nearly doubled in price over the past year, now about $910/ troy oz). I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
