Demystify: 

It better be ab air-tight set up because EtO's PEL-TWA is 1 ppm.  And then the DEP gets into the act at the fume hood stack because there are air quality limits as well.    Monona

Subject: [DCHAS-L] ethylene oxide-THF

Hello,
 
Does anyone have any researchers working with an ethylene oxide/THF solution? This can be purchased from Sigma. We have a researcher that is hoping to make their own by condensing ethylene oxide in THF to make a fresh solution. They are working through the process on paper right now, trying to consider all risk, and I was curious if anyone else has come across a similar situation that they would be willing to share.
 
Thanks,
Stephanie
