Homework Help: Thin layer chromatography

Posted by Sheryl on Wednesday, October 18, 2006 at 10:31pm.

I've done some TLC plates using ethyl acetate with 0.5% glacial acetic acid as a solvent. The structure of these substances looks polar to me. I"m assuming that ethyl acetate is not very polar. Is this correct?

Acetaminophen barely travelled any distance while aspirin went 2/3s of the way up.


Thanks. That helped.
