white crystalline powder | [Uses]
An anti-fade reagent shown to scavenge free-radicals due to flurochrome excitation. | [Definition]
ChEBI: Triethylenediamine is an organic heterobicylic compound that is piperazine with an ethane-1,2-diyl group forming a bridge between N1 and N4. It is typically used as a catalyst in polymerization reactions. It has a role as a catalyst, a reagent and an antioxidant. It is a bridged compound, a tertiary amino compound, a saturated organic heterobicyclic parent and a diamine. | [Preparation]
Triethylenediamine can be produced from ethylenediamine or ethanolamine, diethanolamine, or diethylenetriamine with a variety of different catalysts. | [Reactions]
Triethylenediamine reacts virtually quantitatively with bromine to give a 1/1 adduct. With alkyl halides it forms quaternary salts, even in nonpolar solvents. Apart from its highly nucleophilic nature, triethylenediamine exhibits catalytic activity in base-catalyzed reactions. | [General Description]
Dabco?33-LV (Db) is a gelling catalyst and a bidentate ligand that forms a self-assembled monolayer (SAM) on a variety of substrates. It functionalizes the surface and immobilizes the surface atoms. | [Hazard]
Skin irritant. | [Flammability and Explosibility]
Flammable | [Purification Methods]
DABCO crystallises from 95% EtOH, pet ether or MeOH/diethyl ether (1:1). Dry it under vacuum over CaCl2 and BaO. It can be sublimed in vacuo, and readily at room temperature. It has also been purified by removal of water during azeotropic distillation of a *benzene solution. It is then recrystallised twice from anhydrous diethyl ether under argon, and stored under argon [Blackstock et al. J Org Chem 52 1451 1987]. [Beilstein 23/3 V 487.] |
