Evaporate it. You will end up with sodium carb and freebase dmt. Dissolve this in small amount of naptha, no sodium carb will go in. Filter out soldium carb and freeze precip the naptha.
This should work theoretically.. though not sure why you have a brown chocolate milk solution, that sounds ominous, like oxidized dmt.
