I have found a few things on the internet which lead me to believe that
youmay be able to help me.  I am a Chemistry teacher at Sheldon HS in
Sheldon, Iowa.  I have a student who would like to do some research with
d-Limonene.  Could you help me out?
She would like to get some pure extracts from oranges.  Is there any easy
way to do that?  Or do you suggest something else? Other materials or other
methods?

Thanking you in advance.
