The authors contemplated to find the most preferable method for preparation of methyl hydrogen azelate by the esterification between azelaic acid and methanol. In the first place, authors decided the equilibrium constant, then, specified the composition consisting of azelaic acid, methyl hydrogen azelate and dimethyl azelate in equilibrium with one another at 90°C and 1 atm. By putting the result to practice, authors could establish the condition to obtain the suitable equilibrium composition of the product for preparing methyl hydrogen azelate. The hydrolysis of dimethyl azelate was also discussed by using sodium hydroxide and barium hydroxide in methanol respectively. The result of the experiments showed that the equilibrium method was superior as compared with the latter two cases.
