4-Acryloylmorpholine Chemical Properties,Usage,Production

Description

4-Acryloylmorpholine (4-AM) is a water-soluble monomer, an acrylamide derivative containing a heterocyclic tetrahydrooxazine substituent. Homo- and copolymers of 4-АМ have several valuable properties. They are soluble both in water and in many organic solvents such as alcohols, chloroform, tetrahydrofuran, and dioxane, are non-toxic, and are used for solid-phase synthesis of peptides in chromatography, as materials for composite semipermeable membranes, in catalysis, and for biomedical purposes. Various functional groups are introduced into poly-4-AM to expand its application fields. Random copolymers of 4-АМ with carboxylic acids (acrylic, 4-pentenoic, undecenoic, 2-acrylamido-2-methyl-1-propanesulfonic), behaving as anionic polyelectrolytes, and copolymers with N-hydroxysuccinimide ester of acrylic acid, acting as polymeric carriers, have been synthesized[2-3].

Chemical Properties

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.

Uses

4-Acryloylmorpholine is used in adhesives, UV curable resins, industrial coatings, UV printing ink, oil recovery polymer, medicinal and commodity chemicals.

Reactions

Using cobalt catalysis, diethylzinc promotes the conjugate reduction of 4-acryloylmorpholine to produce the corresponding ethylzinc enolate, which reacts with N-tosyl aldimines to afford β-aminoamides^[1].

Flammability and Explosibility

Non flammable

Synthesis

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%).
