DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
Diisopropylamine is a common amine nucleophile in organic synthesis. [4] Because it is bulky, it is a more selective nucleophile than other similar amines, such as dimethylamine. [5] It reacts with organolithium reagents to give lithium diisopropylamide (LDA). LDA is a strong, non-nucleophilic base [6]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. 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.

A two-step synthesis starts from hydrazine, first by alkylation with ethyl chloroformate, followed by treating the resulting diethyl hydrazodicarboxylate with chlorine (bubbling through the solution), hypochlorous acid, concentrated nitric acid or red fuming nitric acid. The reaction is carried out in an ice bath, and the reagents are added ...
