The Purity of Sulfanilic Acid

Daniel M Marmion

Open publisher page 0 citations

Abstract

Abstract Thirteen samples of sulfanilic acid from various sources were evaluated for purity, using a variety of instrumental and chemical methods. The properties considered include strength, moisture, insoluble materials, iron, sodium, aniline sulfate, orthanilic acid, nictanilic acid, aniline- 2,4-disulfonic acid, and absorptivity. In general, the samples were found to be organically pure and reasonably consistent in quality.
