(Osmium: "Re: MDMA HCL/MDMA sulphate -> ?", Methods Discourse)The sieves consist of Ca or Mg ions (don't know exactly), and therefore are ACID-SENSITIVE!
so, can SWIM use 3A mol sieves when the pH is above 7? When pH is above 7, the acid could have all reacted with the amine right, leaving no acid behind. Is this logic correct?
Meaning, when HCL or other acid is added till pH 8, SWIM would stir the hell out of it and then add the mol sieves to absorb the H2O under non-acidic condition. After stirring for a while, then filter the mol sieves away. Is this method ok?:)
