with zinc diacetate at 65; for 10 h;

Steps:

2 Example 2

0 mmol of isosorbide, 21 mmol of acetic acid, 0.01 mmol of Zn (OAc) 2 was added to 50 mLRound bottom flask. Heated to 65 ° C; at this temperature for 10 h. And then subjected to distillation under reduced pressure to obtain diacetic acidIsosorbide. The isolated molar yield of the ester was 96% and the purity was calculated according to the amount of isosorbide99.5%.
