In the STB extractions, an excess of lye is used. To break up the rootbark and it also makes things easier since a PH checker is not needed.
I'm assuming the excess lye does not come through into the solvent? What if the Naptha is evaporated? What if a different solvent is used (like Xylene)?
Importantly, what if you do an A/B? Just use a big excess of lye to take the PH from acid to very basic? Nothing comes through in the final Product?
