Isopropylamine (monoisopropyl amine, MIPA, 2-Propylamine) 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.[3]
Reactions[edit]
Isopropylamine exhibits reactions typical of other simple alkyl amines, i.e. protonation, alkylation, acylation, condensation with carbonyls. Like other simple aliphatic amines, isopropylamine is a weak base: the pKa of [(CH3)2)CHNH3]+ is 10.63.[4]
Preparation and use[edit]
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst:[3]
- (CH3)2CHOH + NH3 → (CH3)2CHNH2 + H2O
Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.[3] 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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
