would using a typical a/b with vinegar and sodium carbonate, following a typical guide like one used with spice, work?

the pkb of caffeine is higher than dmt (about 10-12), so does this mean a stronger base is needed to make caffeine soluble in the non polar (naphtha)?
 
i've read the stuff online such as the pdf. i'm going to skip the acid part since its soluble enough in water without acid.

how can i figure out how soluble caffeine is in naphtha? it is the only solvent i'll have on hand.
 
hmm, i read the xlogp of caffeine is -0.5 and naphtha being around 4, would make it a poor solvent to use. i could pick up some MEK since its almost right on with caffeine but eh its expensive. this extraction doesn't have to be perfect.

so, is it possible to get some using naphtha or will the caffeine stay in the basified aqueous?
 
no point in commenting about my motives, i do love science ;) there is a hidden reason though :) innocent but cant mention publicly.

yea i'd love to use acetone for a nice quick evap but cant figure out how i'd separate the layers out. lots of salt? i just have very basic tools like turkey baster, crockpot. the only cool lab thing i have is a vacuum pump filter.
