A New Sensitive Method for the Detection and Quantitative Analysis of Ammonia and Aliphatic Amines

摘要

A direct, one-step method is given for the determination of ammonia (and aliphatic amines). The rate of the reaction is so rapid that instantaneous determinations may be made of the ammonia concentrations being sampled. The method requires collection of ammonia in a suitable neutral solvent (e.g., dioxane) containing the reagent, o-(benzenesulfonamido)-p-benzoquinone, and measuring the absorption of light at 480 millimicrons. A proposed reaction sequence is given. (Author)
