化学的特性
4-Acryloylmorpholine has a melting point of ?35 °C and is clear liquid at room
temperature. At 25 °C, it has a density of 1.122 g/mL. It needs to be
stored at 2-8°C.
使用
4-Acryloylmorpholine is used in adhesives, UV curable resins, industrial coatings, UV printing ink, oil recovery polymer, medicinal and commodity chemicals.
合成
A
solution of 0.04 mol of the corresponding amine in 20 ml of anhydrous
methylene chloride was slowly added at 0-5??C to 0.02 mol of acryloyl
chloride in 20 ml of anhydrous methylene chloride. The mixture was
stirred for 3 h at room temperature in an inert atmosphere, and the
precipitate was filtered off and washed with methylene chloride (2 ?á 10
ml). The organic layer was washed in succession with 5 ml of water and 5
ml of a saturated solution of NaHCO3 and dried over Na2SO4, the solvent
was removed under reduced pressure, and the residue was purified by
column chromatography on silica gel using hexane-ethyl acetate (5 : 1 to
1 : 1) as eluent. 4-Acryloylmorpholine, Yield 1.78 g (63%).
