A dream turned into a horror story while attempting to condense Nh3. Am Sulphate/NaOH system was[i] 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? 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
