CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Aniline appears as a yellowish to brownish oily liquid with a musty fishy odor. Melting point -6 °C; boiling point 184 °C; flash point 158 °F. Denser than water (8.5 lb / gal) and slightly soluble in water. Vapors heavier than air. Toxic by skin absorption and inhalation. Produces toxic oxides of nitrogen during combustion. Used to manufacture other chemicals, especially dyes, photographic chemicals, agricultural chemicals and others. |

PRODUCT INTRODUCTION
description
Aniline is a clear to slightly yellow liquid with a characteristic odor. It does not readily evaporate at room temperature. Aniline is slightly soluble in water and mixes readily with most organic solvents. Aniline is used to make a wide variety of products such as polyurethane foam, agricultural chemicals, synthetic dyes, antioxidants, stabilizers for the rubber industry, herbicides, varnishes and explosives
