Hello Everyone! Happy Friday

Quick question - I'm in the process of my first extractions, and a small amount of naphtha from the first pulls remains in my extraction vessel (20-30ml). Can I switch to d-limo at this point?

Would the presence of any naphtha cause problems when using FASx for the remainder of extraction? Still haven't decided on FASW or FASI - is there any clear advantage if I have both fumaric acid & 99% IPA?

I was leaning towards FASW since the fumarates will already be dissolved in h2O and ready to convert to fb with sodium carbonate, but not sure if this is practical.

Thanks!!!
