H20/Hcl extraction

[Vibrating_Lights]

If one was expecting to have .5mole of mdma freebase in 2 L of toulene. then .5mole of hcl would be needed.  Sinceswim has 35%Hcl then aproximatly 50ml would be enough to extract all the amine,  correct?  How much water should be added to the 2 L of toulene prior to the titration?

Do several small extractions. One 100ml One 75ml One 50ml of a 5-10%Hcl solution. It dosnt take a lot of Hcl solution to dissolve youre freebase in. A little goes a long way.
