Could anyone tell me if there is something my friend could use instead of diethyl ether for an extraction, maybe something with a very similar chemical structure.
Obtaining diethyl ether here in the UK is extremely difficult.
Thanks.

EtOAc has a higher dielectric constant, it's too polar. good for chromatographic separations though "Nothing is true, everything is permitted." ~ hassan i sabbah

yup keep in mind, I answered your question from a chemist's point of view.. actually obtaining it as a consumer is a different story. It doesn't exist in most OTC formulations, and is usually ordered (online). a certain popular auction site has it "Nothing is true, everything is permitted." ~ hassan i sabbah
