Diethylene Glycol → Diethylene glycol monoacrylate

Participants

Reaction Steps

25 g (0.235 mol) of diethylene glycol was dissolved in 150 mL of THF. 18 mL of (0.13 mol) of triethyl amine was added, followed by the dropwise addition of 10.8 g (8 mL, 0.12 mol) of acryloyl chloride. The reaction temperature was kept below 30° C. The reaction was allowed to continue for 2 hours at room temperature. The precipitated triethyl amine hydrochloride was removed by filtration, 100 mg BHT was added and the solvent was removed under reduced pressure. Diethylene glycol monoacrylate was purified on a Prochrom LC80-system, using Kromasil 60A 10 μm spherical silica. Methylene chloride/ethyl acetate 60/40 was used as eluent at a flow rate of 200 mL/min. 10 mg BHT was added before evaporation of the eluent. 9.4 g of diethylene glycol monoacrylate was isolated.
