| Abstract: | A method for synthesizing N-methylolacrylamide at 45～50℃, using 28％ aq. solution of industrial acrylamide obtained from hydrolysis of acrylonitrile and 37％ aq. solution of formaldehyde as raw materials, sodium hydroxide as catalyst, and sodium nitrite as polymerization inhibitor, was proposed. The yield reached 72％, and the m. p. of the product is 75℃. The IR spectrum is in concordance with standard spectrum. The reaction factors have been discussed. It is peculiar to this method, compared with the methods of sodium methoxide and ion exchange resin. |
