Subject: Re: Questions out of my realm
Unbelievable! Who is in charge of a student to allow such dangerous procedures? They should be fired for endangerment of life. I'm surprised there was not more damage to the lab itself. 
I'm not chemist enough to advise on how to recrystallize from ether but I know I would never, never have ether in the same room as any heat source.

All,

I got the following two questions from a colleague and since I work in the 
art field, these are out of my area.  Can I get some help?

1.  a student was boiling ether in a large open flask on a stirrer hotplate 
and the fume alone caught on fire, inside the hood. .  Do you have suggestions 
for them to reduce the ether amount for re-crystallization in a safer manner? 

2. a student in was quenching butyl lithium with n-propanol in an open flask 
and it also caught on fire.  Is there a safer way to quench the butyl lithium 
w;ithout catching on fire?
