Title: Ultraviolet and infrared absorption spectra of malonaldehyde in organic solvents

Journal/Source: J. Agric. Food Chem., 16 (4), 639-642, (1968); DOI: 10.1021/jf60158a001


Data: table, diagram

Energy/Wavelength range: 220 - 370 nm

Resolution: 

Temperature: 298 K

Temperature dependence: no

Pressure/Concentration: 2.4 x 10^-3 M

Phase: aqueous solution; diethylether-cyclohexane mixtures

pH: 1; 7


Comments: There are two absorptions bands in diethyl ether (234 nm, 271 nm). The absorbance at 234 nm is about 3 times higher than at 271 nm.
With increasing cyclohexane content, the absorbance at 234 nm gradually fades while that at 271 nm increases.
