D Limonene spill over Sodium Carbonate and Fumaric Acid

[Dante]

Hi Nexian fellas,
Few days ago an acquaintance sold me for a very reasonable price some chemicals that he never managed to use. Unfortunately the Limonene wasnt well sealed, so during the journey back home a tiny bit of it ended onto some sodium carbonate and some fumaric acid. Do you think it would be ok to keep the two chemicals as they are or it would be better to clean them out? I think the limonene in the sodioum carbonate will not create any problem, but Im not sure about the fumaric acid... What would happen if I would use it for a BLAB?
Many thanks

Sodium carbonate and fumaric acid are both cheap and readily available. I would not use either one for anything. Evaporation of limonene will leave a residue; it may be possible to clean them up but why bother?

You are actually right, but I hate to waste things. I think I'll chuck away the fumaric acid and try to clean the sodium carbonate... I'll dissolve it in water and see if there is any limonene floating around.
Thanks

Waste not, want not! Perhaps the same method could be applied to the fumaric acid; the stuff is barely soluble in water though. If one were to use BLAB, it probably wouldn't matter too much if there was some limonene contamination in your FASW, since you will inevitably end up with some anyway.

What are you going to use your fumaric acic and sodium carbonate for? If you use fumaric acid for FASA, for example, the limonene will stay dissolved in your acetone so it wont be in your final product in any significant quantity. The sodium carbonate, when you dissolve it in water, the limonene should rise to the top and form a layer on the surface. You can pipette out most of it, or use a separatory funnel and just get the bottom part.

Lastly, how bad would it be if your alkaloids smelled a tiny bit of limonene?

You can always buy some more I guess but I dont think its too bad, keep what you have

I will probably use the fumaric acid to make some FASI, would it still be alright?

Cool, it's exactly what I wanted to do.

Yeah it should be ok, because FASI will go back to the limonene anyways.

As for the sodium carb, another thing is, it wont dissolve in dry IPA or dry acetone and maybe neither significantly in 96% drinking ethanol, so you can use any of them to wash your sodium carb and remove the limonene (the later two preferable because of lower boiling point / food-safety)

Perfect! Many thanks
