Dipropylamine is a chemical compound selected from the group of the secondary aliphatic amines.

Occurrence

Of course, dipropyl amine occurs in tobacco leaves and in industrial waste. In nature, it decomposes quickly.

Production and representation

Dipropylamine can be obtained by hydrogenation of propionitrile using a rhodium catalyst.

Properties

Dipropylamine has a viscosity of 0.5 mPa · s at 25 ° C and a pH of 11.25 at a temperature of 25 ° C and a concentration of 1 g · l -1.

Use

Dipropylamine is as intermediate for the manufacture of herbicides (for example trifluralin ), drugs, and zeolites.

Safety

The vapors of dipropyl amine can form (7 ° C, ignition temperature 260 ° C flash point) with air to form an explosive mixture. In case of contact with nitrosating agents may result in the formation of carcinogenic nitrosamines.
