Dipropylamine is a chemical compound from the group of secondary, aliphatic amines .
Occurrence
Dipropylamine is naturally found in tobacco leaves and in industrial waste. In the wild, it decomposes quickly.
Extraction and presentation
Dipropylamine, by hydrogenation of propionitrile using a rhodium catalyst are obtained.
properties
Dipropylamine has a viscosity of 0.5 mPa · s at 25 ° C and a pH value of 11.25 at a temperature of 25 ° C and a concentration of 1 g · l −1 .
use
Dipropylamine is used as an intermediate in the manufacture of herbicides (e.g. oryzalin , prodiamine and trifluralin ), drugs and zeolites .
safety instructions
Dipropylamine vapors can form an explosive mixture with air ( flash point 7 ° C, ignition temperature 260 ° C). Contact with nitrosating agents can lead to the formation of carcinogenic nitrosamines .
