N,N'-BIS(2-HYDROXYETHYL)ETHYLENEDIAMINE synthesis
- Product Name:N,N'-BIS(2-HYDROXYETHYL)ETHYLENEDIAMINE
- CAS Number:4439-20-7
- Molecular formula:C6H16N2O2
- Molecular Weight:148.2
Yield:4439-20-7 40.7%
Reaction Conditions:
with sodium carbonate at 135; for 25 h;
Steps:
The syntheses of 1,4,7-trioxa-10,13-diazacyclopentadecane (AA15C5) and 1,4,7,10-tetraoxa-13,16-diazacyclopentadecane (AA18C6) were performed by a modified version of intramolecular cyclization (figure 2) [12]. To a stirred suspension of 2-(2-aminoethylamino)ethanol (208 g, 0.2 M) was added 2-chloroethanol (16.1 g, 0.2 M) and powdered sodium carbonate (16.96 g, 0.16 M). The mixture was stirred at 135 °C for 25 h. After this hadbeen cooled to room temperature, 300 mL of MeOH was added and the mixture was filtered; the resulting solution was evaporated to yield a crude product (yellow oil), which was recrystallized twice from THF over charcoal to give 3 12.05 g (40.7%).
