Isopropylamine (monoisopropyl amine, MIPA) is an organic compound, an amine. It is a hygroscopic colorless liquid with ammonia-like odor. It is miscible with water and flammable. It is a valuable intermediate in chemical industry. The pKa of protonated form is 10.63
Preparation and use
Isopropylamine can be obtained by aminating isopropyl alcohol with ammonia in presence of a nickel/copper or similar catalyst:
(CH3)2CHOH + NH3 → (CH3)2CHNH2 + H2O
Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, Roundup, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione. It is a regulating agent for plastics, intermediate in organic synthesis of coating materials, plastics, pesticides, rubber chemicals, pharmaceuticals and others, and as an additive in the petroleum industry.
Together with isopropyl alcohol it is used in some binary chemical weapons (e.g. M687), as a mixture called OPA which in turn mixed with methylphosphonyl difluoride (known to the military as DF) produces sarin gas.
