2,3,4,5,6-Penta-O-acetyl-D-glucose Use and Manufacturing
A solution of D-glucose (0.36 g; 2 mmol) in N, N'-dimethylimidazolium or N, N'-butylmethyl methyl H-phosphonate (1 g) is treated with acetic anhydride (1.02 g; 10 mmol) at room temperature under stirring. The reaction is exothermic; the mixture becomes homogeneous. After 15 hrs at room temperature or 5 hrs at 50° C., glucose penta-acetate is precipitated by adding water (m=0.72 g; yield=92percent).General procedure: To a stirred solution of VO(acac)
25,000 - 100,000 lb
