| Abstract: | Dimenthyl malate was prepared from malic acid and menthol through direct melt esterification.The optimum preparation conditions were toluene- p -sulfonic acid as catalyst, w (toluene- p -sulfonic acid)=1 .5%, n (menthol)/ n (malic acid)=2 .4,reaction time 5 h and reaction temperature 120 ℃.The yield was 61 .5%.Structure of dimenthyl malate was confirmed by IR,MS and NMR.Furthermore,pyrolysis of dimenthyl malate at 300 ℃,600 ℃ and 900 ℃ was studied. |
