Reaction Conditions:

at -15; for 0.333333 h;Milling;

Steps:

2 Example 2-7

(1) Weigh 100g of anhydrous glucose and30g sodium acetate (sodium acetate both as a catalyst but also as a grinding aid), one-time added to the ball mill tank, weighed 1L acetic anhydride divided into 6 batches added at -20 , speed 200r / min for 20min.(2) After the ball mill with 5L water flush tank wall,The mixture in the ball mill jar was collected, stirred in an aqueous solution for 10 min, washed with excess sodium acetate,Acetic anhydride and acetic acid produced by the reaction. Filter and dry to obtain β-pentaacetylglucose.; The same procedure was followed as in Example 1, except that the reaction temperature varied. The specific temperature for Example 2-7 was chosen to be -15 ° C, -10 ° C, -5 ° C, 0 ° C, 20 ° C and 40 ° C.The β-pentaacetylglucose obtained in Example 1-7 was weighed, the yield and selectivity were calculated, and the purity of β-pentaacetylglucose was measured by HPLC:
