Abstract: cf. CA 63, 3622d. The total HCO₂H formed during periodate oxidn. of maltose was detd. The aldehyde group was changed into formyl ester which represented one half of the free forming HCO₂H. The reaction occurred at pH 7.0. After the periodate oxidn. of maltose, contg. 1 to 3 mg. HCO₂H, 0.5 ml. ethylene glycol was added and the soln. let stand for 15 min. at room temp. Then 5 ml. 0.4M KI and 10 ml. 0.01N Na₂S₂O₃ were added. After standing for 4 hrs. at room temp. the soln. was titrated with 0.01N I (loc. cit.).
