Some idiot did a naptha extraction to fatwash HWBR and MG, let the washed powder evap for 48 hours until was completely dry, the put in cold water and let soak. The alkaloids cleraly and absorbing into the water as it changed to a yellowish color, however one major problem remains, there is small bubbles on top of the water.

Is there naptha remaining?

LSA is heat sensitive so a hair dryer cant be used to evap any remaining naptha.

So temp solution has been to let solutions seperate hoping that the naptha is floating and have it in front of a fan? Will this remove then naptha?

What can I do to make sure theres none left, should I freeze it? Im so lost.

Naphtha should rise to the top in an acqueous solution, but it might be too litte to be able to pippette it out. I guess you could indeed freeze it, and then the acqueous part would be frozen, and then you could wash the top part of the frozen solution with ethanol or acetone, which should pick up the naphtha and leave the clean frozen solution behind.

Be well

Thank you, thats a really good idea. =D
