A SEMIQUANTITATIVE METHOD FOR THE DETECTION OF ACETIC ANHYDRIDE IN ACETIC ACID
Keyword(s):
When acetic acid is handled in aluminum, it is important, for reasons of corrosion resistance, that the acid be not completely anhydrous, a condition that results if traces of acetic anhydride are present. A quick colorimetric test depending on the reaction between acetic anhydride with aniline has been developed by which it is possible to detect 0.05% acetic anhydride in acetic acid.
