Abstract
β-GLUCOSE pentaacetate in acetone solution can be partially deacetylated by cooled 1 N potassium hydroxide solution to yield 6-O-acetyl-α-glucose. This product has a melting point of 146°. It has been identified by analysis, molecular-weight determination, downward mutarotation to +53° and hydrolysis to glucose and acetic acid. Periodate oxidation requires 4 moles of periodate per mole 6-O-acetyl-α-glucose without yielding formaldehyde, but glycol-aldehyde as p-nitrophenyl ozazone could be isolated as a product of oxidation. 6-O-acetyl-α-glucose cannot be tritylated, but a phenylosazone of it has been prepared, m.p. 171°.
