Octylamine is a chemical compound from the group of amines , more precisely the monoalkylamines .
Occurrence
Octylamine occurs naturally in apples.
Extraction and presentation
Octylamine, by hydrogenation of Octandienylamin be obtained, which in turn by telomerization of 1,3-butadiene with ammonia can be obtained.
properties
Octylamine is a colorless liquid with an amine-like odor that is practically insoluble in water.
Safety-related parameters
Octylamine forms flammable vapor-air mixtures above the flash point. The compound has a flash point at 60 ° C. The explosion range is between 1.6% by volume as the lower explosion limit (LEL) and 8.2% by volume as the upper explosion limit (UEL). The ignition temperature is 265 ° C. The substance therefore falls into temperature class T3.
use
Octylamine is used as a corrosion inhibitor, in flotation and as an asphalt emulsifier. It is contained in fabric softeners , detergents , vulcanization accelerators , printing inks and toners. It is used as an intermediate for various other chemical compounds such as octenidine , an antimicrobial and biocidal agent for various applications, and N- octylpyrrolidone .
