| Abstract: | Methyl 3-methoxypropionate was prepared from methanol and methyl acrylate using sodium hydroxide as catalyst and NaHSO 4 as neutralizer.The optimum conditions were determined by optimizing the single factor:the ratio of methanol to methyl acrylate is 1.5 to 1 with 10% NaOH,reaction temperature 55 ℃ and reaction time 6h.The total yield of MMP could reach 97% or more and the purity of the product was more than 99.5%. |
