실험 절차

Synthesis of a vinyl ether monomer. 2-Vinyloxy Ethyl Phthalimide was prepared via reacting 2-chloroethyl vinyl ether (25 g, 0.24 mol) and potassium phthalimide (25 g, 0.135 mol) in 100° C. DMF (75 ml) using tetra n-butyl ammonium bromide (0.5 g) as the phase transfer catalyst. This solution was heated for 6 h and then crashed out in water and filtered. This solid was then recrystallized twice from methanol to give white crystals.
