Applications |
2-Ethyl-2-oxazoline It is mainly used in Intermediate in organic syntheses. New thermo-responsive polymer materials Poly(2-ethyl-2-oxazoline). Typical procedure. To a flame dried round bottom flask (250mL) fitted with a nitrogen inlet and a rubber septum were added 32 ml of chlorobenzene and 18 ml (178 mmol) of 2-ethyl-2-oxazoline. At a temperature of 110˚C and under nitrogen the polymerisation was initiated by adding 100 l (0.88 mmol) of methyl triflate The reaction mixture was stirred for 19 hours. During the course of the reaction the solution turned from clear colourless to clear yellow. To the reaction mixture was added 0.8 ml (8.8 mmol) of morpholine. The reaction mixture was stirred for another 4 hours at 110˚C and then cooled down to room temperature. The solution was poured into an excess of cold diethyl ether and the precipitated polymer was isolated by decanting the solvent. The polymer was purified by precipitation from acetonitrile into ether twice.Yield 16.8 g (96%) of a yellow solid. 1H-NMR (CDCl3) showed absence of residual chlorobenzene.
