Versuchsvorschrift
Add 2 g of triethylene tetraamine (with an AV of approximately 1180 mg KOH/g) to 20 ml of toluene in a 250 ml flask fitted with a stirrer, condensor and nitrogen inlet. Add 1.21 g ethylene carbonate to the mixture. Reflux the system for 2.5 hours under N2. Strip the system to yield an ethylene carbonate-triethylene tetraamine adduct having an AV of approximately 507 mg KOH/g.
