| Abstract: | 3-Dimethylamino-N,N-dimethylpropionamide(DMDMAA) was synthesized from methyl acrylate and dimethylamine with methanol as solvent and sodium methoxide as catalyst.The optimum synthesis conditions were that the mass ratio of sodium methoxide was 2.8 % of methyl acrylate,reaction temperature was 20~30 ℃,the volume of fraction of methanol was 50 %.Under these conditions,the yield of DMDMAA was 62.8 %,with the purity of 99.5 %.The structure of DMDMAA was confirmed by IR spectrum and MS spectrum. |
