Cashew Oil.. failed
I've been grinding cashew kernels into a fine powder and then using my soxhlet extractor with ethanol.
I boiled the extract down to remove ethanol but I was left with a water soluble liquid and a thick tar like substance that stuck in a coffee filter.
I think I'm approaching this incorrectly.

Ethonal is polar, most oils are non polar. Hope this helps
Edit: i need tostart reading twice before i post.
Many of the compounts found in food are tempature sensitive.
Using a vacuum to reduce the heat required to remove the solvent may be required
Any specific target your look8ng to collect?

Thanks, this weeks homework is to learn properly which solvents are which, I had good results with acetone and walnut oil but used ethanol this time
as I have more of it.

You can maybe obtain medicinal petrolether, it is usually a mixture of isohexanes with b.p. 60-70 C.
