Promethazine dm extraction

[Tryptamine420]

Is there an extraction method to get dxm and promethazine powder out of syrup containing dxm, promethazine and alcohol? Alcohol content is low, between 5 and 7% not sure which.

What - 2 piles of pure material?

Acid/base

 

[negrogesic]

I am trying to wrap my mind around the reasoning for such a procedure....dxm can be found in bulk for cheap.........?
