Abstract
In ordinary manufacturing of anionic surface active agents, sulfation or sulfonation is a major part. Nonaqueous titration method, dodecyl trimethyl ammonium hydroxide as a titrant, isopropyl alcohol as as a solvent, was available for analysis of the acid-intermediates.
In this method, a correction of the first inflections based upon impurites in the titrant was necessary, but the experimental results with various acid mixtures and sulfonated matters were quite satisfactory.
