I'd suggest tartaric or maleic; and I have a feeling you're going to make a mess and lose product if you use limonene. LSA isn't as forgiving as DMT, with regards to hippy fad teks.

*edit* - you don't necessarily need inert gas for the extraction, but dim lighting is necessary, or you'll see a clear solution turn beige, then amber. Once it's complexed with a dicarboxylate, it is rather stable. store in amber glass in the freezer.

right...

but why would you want to add ascorbic acid? there's no advantage over tartaric;
and you're not going to displace the tartrate cation by adding ascorbic acid, tartaric acid has a lower pKa.


and I'd use toluene or xylene instead of limonene; dcm for the extraction.

*edit*...nm the latter..the former solvents would form a bilayer with alcoholic tartaric acid, which is what you'd want for the extraction. alcohols tend to mix with dcm
