Thank you! We’ve been discussing discontin uing dichloromethane at our community college. We’ve had some succes s using petroleum ether for chromatography, but are unsure what to use as a substit ute for the bromine in dichloromethane test for unsaturation. We have the students use the Baeyer Test but would also like to do a bromine test, if possible.
Suggestions from the DCHAS community would be greatly appreciated.

I found out today that one of our teaching labs is conducted an extraction experiment with dichloromethane (caffeine from coffee)
I would like to provide them a reasonable alternative extraction experiment w ith an occupationally regulated carcinogen…
If you have a recommendation to look at, would you please contact me?
