Abstract: Methyl p-methoxy cinnamate was synthesized by Claisen-Schmidt condensation from p-methoxybenzaldehyde and methyl acetate using sodium methoxide as catalyst.The effects of factors such as catalyst kinds,n(p-methoxybenzaldehyde)∶n(methyl acetate),amount of catalyst,reaction temperature and time on reaction results were examined.The obtained optimum conditions were n(p-methoxybenzaldehyde)∶n(methyl acetate) =1∶8,amount of sodium methoxide 10wt%,reaction temperature 50 ℃ and reaction time 1.0 h.Under above conditions,the yield and purity of the product were 79.0% and more than 99.0% respectively.The structure of the obtained product was confirmed by FT-IR,1H NMR and melt point.
