Procedure
Add 56.7 g of tetraethylene pentaamine (with an AV of approximately 1050 mg KOH/g) to a 250 ml flask fitted with a stirrer, condensor and nitrogen inlet. Add 26.4 g ethylene carbonate to the system. Heat the system at 160° C. for 3 hours under N2. Strip the system to yield an ethylene carbonate-triethylene tetraamine adduct having an AV of approximately 540 mg KOH/g.
