Triethylamine in water
WebWeakly alkaline amines pose no problems in the water determination after Karl Fischer and can be titrated according to standard methods. For strongly alkaline amines the buffer capacity of the Karl Fischer solution is not sufficient. A shift of pH into the alkaline range leads to a side reaction of the iodine. WebThe amine still contains the nitrogen lone pair, and does exactly the same thing. For example, with ethylamine, you get ethylammonium ions and hydroxide ions produced. CH 3CH 2NH 2(aq) + H 2O(l) − ⇀ ↽ − CH 3CH 2NH + 3 (aq) + OH − (aq) There is, however, a difference in the position of equilibrium. Amines are usually stronger bases ...
