cf. C. A. 24, 21. The following substances do not cause selective absorption of ultra-violet light between 4900 and 2100 A. U.: cellobiose (in H2O), raffinose, acetylcellobiose, β-acetyllactobiose (in CHCl3), acetylsucrose (in CHCl3), acetylmaltose (in CHCl3). The 2 absorption bands with maximum at 2680 and 3200 A. U., which appear when glucose is treated with NaOH in weak concentrations (C. A. 26, 5078) are probably due to the aldehyde form, for if the NaOH is neutralized with HCl after a short time, the original spectrum showing practically no selective absorption is obtained. Prolonged action of OH– on glucose gives a product showing selective absorption which does not disappear on addition of acid.
