Mysterious white powder - No Nh3!
« on: January 27, 2003, 01:56:00 PM »
A dream turned into a horror story while attempting to condense Nh3. Am Sulphate/NaOH system was running 100% to plan, chiller -15C, condensor -53C, but all that was produced was a white (annie) smelly powder in the condensor/flask. I vaguely remember reading a post from dwarfer or Mr Clean about ammonia reacting with CO2/dry ice, could this be the cause? Drier is large PVC/CaCL2 tube (runs quite hot 35+ deg C) and yet some moisture is still getting to condensor.(which would explain heat, but not the white powder) Ideas anyone? ::)

Are you sure its not frost?

Are you sure its not frost? If any water vapor goes through than your condensor at -53C is going to get frost in it. Maybee try using NaOH for the drying tube. Its much more hygroscopic.

You have a complex of ammonia and calcium chloride, obviously you have a lot more to learn about basic chemistry  ;)  Here's some posts that state this, which you could have found using the fucking search engine:
