Isopropylamine, also called 2-aminopropane, 2-propanamine, monoisopropylamine, and MIPA, is an organic compound, an amine. It is a base, as typical for amines. It is a hygroscopic colorless liquid with ammonia odor. Its melting point is -95.2 °C and its boiling point is 32.4 °C. It is miscible with water. It is extremely flammable, with flash point at -37 °C.
Isopropylamine can be obtained by aminating isopropyl alcohol with ammonia in presence of catalyst:
- (CH3)2CHOH + NH3 → (CH3)2CHNH2 + H2O
The main uses of isopropylamine are as the salt component to glyphosate acid for weed prevention (aka Roundup), a key compenent to Atrazine (another herbicide), a regulating agent for plastics, intermediate in organic synthesis of coating materials, plastics, pesticides, rubber chemicals, pharmaceuticals and others, and as an additive in petroleum industry.
Together with isopropyl alcohol it is used in some binary chemical weapons, as a mixture called OPA which in turn mixed with methylphosphonyl difluoride (known to the military as DF) producing sarin gas.
