Air & Water Reactions
Highly flammable. Insoluble in water.
A water-white liquid with an ammonia-like odor. Less dense than water and insoluble in water. Flash point 75°F. May be moderately toxic by ingestion, inhalation and skin absorption. Very irritating to skin, eyes, and mucous membranes. Used as a solvent and to make pharmaceuticals.
Dry it by refluxing with BaO or sodium, then fractionally distil it through a helices-packed column. The picrate has m 227o, the thiocyanate salt has m 103o (from butanone). [Hall J Phys Chem 60 63 1956, Beilstein 27 I 203, 27 III/IV 22.]
Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
