Specific Features of N-Morpholinoethyl Methacrylate Synthesis

详细

Methods for synthesis of N-morpholinoethyl methacrylate were compared. It was shown that the monomer produced by acylation of N-morpholinoethanol with methacrylic acid anhydride or methacryloyl chloride spontaneously polymerizes in storage. The possible reasons for the spontaneous polymerization of N-morpholinoethyl methacrylate produced by the acylation method were considered. The conditions in which a stable-in-storage monomer can be obtained in 86–88% yield by the method of re-esterification of methyl methacrylate with N-morpholinoethanol were determined.
