Dipropylamine Usage And Synthesis
Chemical Propertiescolourless liquid
Chemical PropertiesDipropylamine, like the other short chain aliphatic amines, is a very strong base, its reactivity being governed by the unshared electron pair on the nitrogen atom. It forms a hydrate with water. The amine also can react with inorganic or organic nitrites under acidic conditions and possibly by reaction with nitrogen oxides from the air to form the highly mutagenic and carcinogenic N-nitrosodipropylamine (ATSDR 1979; Olah et al; Scanlan 1983).
Usesn-Dipropylamine is a useful reagent for the preparation of perylene derivatives for photosensitive fluorescent resins.
Production MethodsDipropylamine is manufactured by reaction of propanol and ammonia over a dehydration catalyst at high temperature and pressure (HSDB 1989). Alternatively, propanol and ammonia can be combined with hydrogen over a dehydrogenation catalyst. In each instance, the resulting mixture of primary, secondary, and tertiary amines can be separated by continuous distillation and extraction (Schweizer et al 1978). Dipropylamine is a natural component of vegetables, fish, fruits, and other foods (Mohri 1987) and of tobacco products (WHO 1987). It also is found in human urine (Audunsson 1988), waste water lagoons (Guzewich et al 1983) and in workplace air (Simon and Lemacon 1987).
The toxic compound, N-nitrosodipropylamine, can be produced inadvertently by nitrosation of n-dipropylamine during various manufacturing processes that use the diamine (ATSDR 1989). The nitrosamine, therefore, occurs as an impurity in some dinitroaniline pesticides and rubber products. N-nitrosodipropylamine also is found in various foodstuffs including cheese, cured meats, cooked fish and alcoholic beverages, apparently by reaction of n-dipropylamine with the preservative sodium nitrite (ATSDR 1979; Gross and Newberne 1977; Scanlan 1983).
General DescriptionA clear colorless liquid with an ammonia-like odor. Flash point 30°F. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion.
Air & Water ReactionsHighly flammable. Soluble in water.
