yes. typically big ones like S****-A****** will play 20 questions and request a company letterhead. they usually refuse to sell to individuals "Nothing is true, everything is permitted." ~ hassan i sabbah

yeah, that sort of pacifism is typical of complacent right-wing ideology. i won't rant about it here, but it's a sad aspect of the status quo; big brother's effort to protect us from ourselves  "Nothing is true, everything is permitted." ~ hassan i sabbah

Limonene can be distilled from orange oil. Since Limonene constitutes 90%+ of orange oil, and the common impurities boil at a lower temperature, you can distill off the first fraction... and collect the remaining Limonene at 176C, being careful not to top 198C where other impurities boil.

Just mix in some water and it distills along with it. Pretty cool. Correct me if I'm wrong but this means that if I put boiling water into used D-limonene and mix, let separate and pull the D-limonene, it will be clean again. PEACE

Well, you may be able to separate impurities from orange oil if they're water soluble (and assuming limonene isn't.. is it?)... but there are still other solvents in the <5% range occupying orange oil besides limonene- refer to the wikipedia article on orange oil.
