Hexamethyleneimine Usage And Synthesis
Chemical Propertiesclear colorless to light yellow liquid
UsesA degradation product of herbicide Molinate in pot soil and rice plants.
DefinitionChEBI: An azacycloalkane that is cycloheptane in which one of the carbon atoms is replaced by a nitrogen atom.
General DescriptionA colorless liquid with an ammonia-like odor. Flash point 65°F. Toxic by ingestion. Corrosive to metals and tissue. Combustion produces toxic oxides of nitrogen.
Air & Water ReactionsHighly flammable. Soluble in water.
Reactivity ProfileHexamethyleneimine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.
HazardToxic by ingestion, strong irritant to tissue.
Health HazardInhalation of vapor irritates respiratory tract; high concentrations may cause disturbance of the central nervous system. Ingestion causes burns of mouth and stomach. Contact with concentrated vapor may cause severe eye injury. Contact with liquid causes burns of eyes and skin.
Purification MethodsPurify azepane by dissolving in Et2O and adding ethanolic HCl until all the base separates as the white hydrochloride, filter, wash with Et2O and dry it (m 236o). The salt is dissolved in the minimum volume of H2O and basified to pH ~ 14 with 10N KOH. The solution is extracted with Et2O, the extract is dried over KOH, evaporated and distilled. The free base is a FLAMMABLE and TOXIC liquid, and best kept as the salt. The nitrate has m 120-123o, the picrate has m 145-147o, and the tosylate has m 76.5o (ligroin).
