No-Aqueous Titrations: Potentiometric Titration of Some Primary Amines

open access: yesReviews in Analytical Chemistry, 2008
Potentiometric titrations of some primary amines; I-aminobutane, Iaminopropane and 3-amino-l-phenylbutane were carried out with hydrochloric acid in toluene solvent. The same titrations were done with hydrochloric acid in methanol solvent to show the effect of amphiprotic solvent in the titrations with hydrochloric acid.
