Triethylenediamine Chemical Properties,Uses,Production

Chemical Properties

white crystalline powder

Uses

An anti-fade reagent shown to scavenge free-radicals due to flurochrome excitation.

Hazard

Skin irritant.

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.]
