The Radiolysis of Aqueous Acetonitrile: Compounds of Interest to Chemical Evolution Studies

Authors: I.G. Draganić, S. Jovanić, V. Niketić, Z.D. Draganić, Oxygen-free aqueous solutions of CH3CN (0.1 M, pH 6) were ex- posed to gamma rays from a 60Co source,the mixture of non volatile radiolytic products was fractionated and the fractions were analysed. Succinic,maleic, fumaric, malonic andpyruvic acids were identified. Glycol aldehyde,glucose and probably ribose were observed in the hydrolysate of fractionated…

The Radiolysis of Aqueous Ammonium Cyanide: Compounds of Interest to Chemical Evolution Studies

Authors: Z. D. Draganić, V. Niketić, S. Jovanović, I. G. Draganić Oxygen-free aqueous solutions of NH4CN (0.1 M, pH 9) were exposed to gamma rays from a60Co source, the mixture of nonvolatile products was fractionated, and the fractions were analyzed. The procedures were chosen to make effective investigations of radiolytic products, and to minimize the contributions of chemical changes which…

Pulse Radiolysis Study of Alcohols in Aqueous Solution

Authors: M. Simic, P. Neta, E. Hayon A detailed pulse radiolysis study of aqueous solutions of methanol, ethanol, isopropyl alcohol, n-, iso-, and t-butyl alcohols, neopentanol, and eyelohexanol has been carried out. Optical absorption spectra of some of the transients have been measured down to 210 nm. Similar spectra were obtained in liquid methanol, ethanol, and isopropyl alcohol. Absorption maxima…
