Seperating amine salt from sulfonyl amide
« on: November 06, 2015, 02:49:10 PM »
Hello fellow chemists,
today by a mistake i mixed wrong flasks together, and contaminated my pure product.Now i have mixture of amine trifluoroacetate salt (like 80%) and sulfonyl amide.I guess there is no point of performing chromatografy, because amine salt is way too polar.I was thinking perhaps there is a way, that  i could extract  amine salt from organic phase with water? What could be right conditions for the salt to dissolve in water? Im adding an image of structure of molecues.

If your salt is soluble in water while the other compound is not then its easy. I think chromatography might work too - you firstly elute your starting material and then your salt using methanol with some base
