adapter stuck on my reaction flask

[alterego]

Hi there,
Quick question;
my adapter got stuck on the reaction flask. ( there was a lot of heat and pressure, and i manupulated somethimes the reactions by cover up the reflux end for a second with tumb). Used Ai/Hg btw.
Any suggestions?

alteregoPut the adapter under boiling water or use octane brander and try to loosing it. Better 20 small left rights then one strong right because you will break it.

You didnt use vaseline

Heat the female part with a hot-air gun, hairdryer with nozzle, hot-air soldering thingie, heat evenly around and only the female part. Rock the parts left-right and back-forth and then twist hard. Didn't work? Add some drops of concentrated sulfuric acid for a few hours so it can seep into the joint, wash off, try to twist if not apply heat again and try again.

Did not work? Thats where I smash the less valuable part to save the more important one.

So got them seperated ( without cracking) .
Thx for the tips guys.
I heated the female joint, and twisted it ( with welding gloves, so got no grip) was not a succes.
Then i used a tapped hammer ( rubber head) and gave it like 1000 mini taps ( literly no force was used , only for vibration needs). Then the waterseal between plugs started to chance, and i know it was the moment! pulled it out in a straight motion ( still there was a like force required, but no damage)
Me happy now! That the brand new flask is not damaged due to a cheap chinese 24/40 adapter from a couple of bucks...

Heat guns are very useful for unfortunate situations like those; so are 15$ BBQ gloves that let you grab the hot glass. A good hairdryer is as good as a heat gun, but might take longer to heat the glass to the needed temperature for separation.
