HCID 76607Methyl glucoside

Procedure

In a manner similar to that described in Example 3, 300 parts by weight of D-glucose obtained from used paper was added to 1,100 parts by weight of a methanol solution containing hydrochloric acid at a concentration of 0.25 wt % and was then refluxed for 72 hours, whereby 160 parts by weight of methyl-D-glucopyranoside was obtained. The measurement results are shown below.
