Triethylamine → HCID 86734348, compound

Participants

Reaction Steps

60 g (0.208 mol) of N,N'-bis-(3-chloropropionyl)-sulphuric acid diamide are dissolved in 1 l of absolute acetone. 100 g (0.99 mol) of absolutle triethylamine are added over the course of 15 minutes from a dropping funnel. The mixture is stirred at room temperature until no further precipitate forms and is filtered. The filtrate is concentrated until crystallisation commences. It is then allowed to complete crystallisation at 10°C and after filtration, washing with absolute ether and drying N,N'-bis-acryloyl-(sulphuric acid diamide) mono-triethylamminium salt of melting pont 104°C is obtained. This can be purified further by recrystallisation or can be obtained as free N,N'-bis-acryloyl-sulphuric acid diamide by dissolving in water and acidifying with hydrochloric acid.
