Swim was making MeNH2 with Formalin/NH4Cl At 65°C and vacuum Approx 20". CO2 was comming nicely and had very slight reflux, then after 15 minutes, solution turns clear and tiny lovely CO2 gone. Second frigging time.
This was Swims second run with the same thing happening. First run yielded about 2g! Swims Formalin was about 2 years old and on the second synth I noticed polymerised powder on the bottom of the bottle, which was mixed for inclusion in the second synth.
So does Formalin decay over time? Swim should be seeing CO2 for hours. Can't recall reading any post about CO2 disappearing. I know the differance between CO2 and boiling bubbles. It's the Formalin man. What else could it be?
