Ullschmied In a mixture of molecular gases with compositions (CO2–N2–H2O and CO–N2–H2O) and total pressure close to that of the EarthÕs early atmospheres, a centimeter-sized plasma was created by focusing a single 85-J, 450-ps…

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…
