Title: TLC of safrole, halosafrole, azide and amine.
Post by: Atropos on August 12, 2002, 03:04:00 AM
What would be a good TLC mixture for these compounds?
20:1 and 8:1 DCM/MeOH is ineffective on silica, as is 4:1, 2:1 Hexane/EtOAC.
Suggestions?

If you had used the search engine,

(lugh: "Characterization of Essential Oils", Methods Discourse) and

96:4 Toluene/Ethylacetate is just what the doctor ordered! Trust me, you wont be dissapointed.

lugh (is that as in Lugh the Long Handed?), I actually did search on the engine (I search a hell of a lot more than I post, check out my registration date), but the combinations of words I used turned up many useless posts. I apologize if this post is redundant.
Ritter, thanks a million! That's what I needed to hear. Several more useless combinations have reared their ugly heads, and I never would have thought of toluene as a primary solvent.
Trust you?!? I've read your posts, and trust your information implicitly. You are a font of useful data...

5:1 Hexanes:Ether, the alkene will have a Rf of 0.8, and the Ketone will have a Rf of 0.2, and the Amine 0.1
