  2. N,N-Diisopropylethylamine - Wikipedia

    en.wikipedia.org/wiki/N,N-Diisopropylethylamine

    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.

  3. Diisopropylamine - Wikipedia

    en.wikipedia.org/wiki/Diisopropylamine

    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]

  4. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    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.

  5. Isopropylamine - Wikipedia

    en.wikipedia.org/wiki/Isopropylamine

    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.

    This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.

  7. Lithium diisopropylamide - Wikipedia

    en.wikipedia.org/wiki/Lithium_diisopropylamide

    Lithium diisopropylamide (commonly abbreviated LDA) is a chemical compound with the molecular formula LiN(CH(CH 3) 2) 2.It is used as a strong base and has been widely utilized due to its good solubility in non-polar organic solvents and non-nucleophilic nature.

  8. QL (chemical) - Wikipedia

    en.wikipedia.org/wiki/QL_(chemical)

    Isopropyl aminoethylmethyl phosphonite (NATO designation QL), also known as O-(2-diisopropylaminoethyl) O ′-ethyl methylphosphonite, is a precursor chemical to the nerve agent VX and VR-56. It is a colorless liquid with a strong fishy odor, and is slightly soluble in water.

  9. Diisopropyl ether - Wikipedia

    en.wikipedia.org/wiki/Diisopropyl_ether

    Diisopropyl ether is a secondary ether that is used as a solvent. It is a colorless liquid that is slightly soluble in water, but miscible with organic solvents. It is used as an extractant and an oxygenate gasoline additive. It is obtained industrially as a byproduct in the production of isopropanol by hydration of propylene. [3]
