Reaction Steps

Into a 250 mL vessel, hexaglycerol (5.0 g, 10.81 mmol) was added and dissolved into anhydrous THF (50 mL). Octanoic acid (13.71 mL, 86.49 mmol) was also dissolved into the reaction mixture which was stirred magnetically at room temperature for one hour to fully dissolve the reagents. N,N-dimethylaminopyridine (0.132 g, 1.08 mmol) was dissolved in the solution. When the catalyst was fully dissolved, EDC HCl (16.6 g, 86.6 mmol) was pipetted into the vessel and was sealed to keep the reaction dry. The reaction proceeded overnight at 55° C. The solution was stripped of THF via rotoevaporation and redissolved into chloroform. The organic layer was washed 2× with sodium bicarbonate buffer and 2× with deionized water to remove unreacted starting materials. The chloroform was removed to yield a clear viscous liquid. NMR analysis supported full conversion of hydroxyl groups to the octanoic esters.
