Hello brothers, first extraction.

I have approximately 350-400g of Acacia Acuminata Bark (inner fibers stripped out and blended with also a mass of far less strips of bark) in a Slow-Cooker with a enough solution of 1/4 White Vinegar and 3/4 Water to completely it. It has been there for over an hour now, and this is my third acid cook. I will reduce all three down to approx 1 liter.

I have also just had a batch of approx 250g of Sodium Carbonate finish decomposition in the oven.

I plan to do an A/B extraction with Naptha as my solvent

After all this preparation I have just started reading in several threads that I cannot use Sodium Carbonate to basify when using naptha as a solvent.

I still don't quite understand why not, so am i am looking for explanations. I apologize if this information has been shared too many times.
If there is no way around this is there any other tek i can use from where i have already gotten to which allows me to use Naptha and Sodium Carbonate.

thankyou for viewing this post and i hope you can help.

Sodium carbonate is not very strong base, so your yield might be small.. Also, when you add it to your acacia solution, it will bubble up from CO2, so be sure to add slowly if you do. Also the problem is that it tends to create a lot of emulsions.

One thing you could try doing is, after filtering your acacia solution, reduce it down to a goo, and then do a dry tek on that by mixing with sodium carbonate to make a paste, mix well, then dry and pull with your solvent. If you can find calcium hydroxide, its a stronger base for dry teks, but otherwise you can try with sodium carb. This would prevent the emulsion problems, the sodium carb would be much more concentrated and probably basing better, and with warm naphtha, its possible the yield would be decent.

Whatever way you go, just dont throw anything away, because if yields are not as desired, you can always later use a stronger solvent and/or add a stronger base or similar.

Let us know how it works out for you
