摘要: Molar absorptivities have been determined for glyoxal and gluteraldehyde in aqueous solution. Absorptivities are reported at eight temperatures the range 5-70 degrees C wavelengths greater than 200 nm. For data indicate did less 0.02% of molecules exist free dialdehyde form, that 25 approximately 98% hydrated both carbonyl groups, results consistent with previous experiments. hydration two groups occurs an independent manner. The following thermodynamic found hydration: deltaH = - 35.8+/-1.3 kJ mole(-1), deltaS 103+/-7 J (mole K)(-1), K 7.5+/-2.0. compared obtained aliphatic aldehydes.
