@Raybhayes1: I see you’ve posted a link to your SOP elsewhere.
the first thing that jumps out is
…We use at a minimum 10:1 ratio of ethanol to crude for dilution.
that should be maximum 10:1 dilution. dilute too far, and your waxes won’t fall out…
others with Apeks or CO2 in general experience should be able to provide feedback on your actual run parameters.
are you decarbing your input material first?
you don’t mention that. and you seem to have a decarb step in your rotovap.
I believe decarbing first will help with yield with your current procedure, but don’t take my word for it…
