| The merchandise covered by this order is all grades of sulfanilic acid, which include technical (or crude) sulfanilic acid, refined (or purified) sulfanilic acid and sodium salt of sulfanilic acid (sodium sulfanilate). |
Sulfanilic acid is a synthetic organic chemical produced from the direct sulfonation of aniline with sulfuric acid. Sulfanilic acid is used a a raw material in the production of optical brighteners, food colors, specialty dyes, and concrete additive. The principal differences between the grades are the undesirable quantities of residual aniline and alkali insoluble materials present in the sulfanilic acid. All grades are available as dry free flowing powders.
Technical sulfanilic acid contains 96 percent minimum sulfanilic acid, 1.0 percent maximum aniline, and 1.0 percent maximum alkali insoluble materials. Refined sulfanilic acid contains 98 percent minimum sulfanilic acid, 0.5 percent maximum aniline, and 0.25 percent maximum alkali insoluble materials. Sodium salt of sulfanilic acid (sodium sulfanilate) is a granular or crystalline material containing 75 percent minimum sulfanilic acid, 0.5 percent maximum aniline, and 0.25 percent maximum alkali insoluble materials based on the equivalent sulfanilic acid content.
