Notizen: Abstract Cotton cellulose was irradiated under oxygen or nitrogen atmosphere with60Co irradiator in the dose range 0-130 kGy. The following compounds were found: acetaldehyde, acetone, arabinose, desoxysaccharides, formaldehyde, formic acid, glucuronic and gluconic acids, glucose, malonaldehyde, oxalic acid and xylose. No changes were observed in qualitative composition of radiolytical products formed in oxygen and nitrogen atmospheres. On the other hand the presence of oxygen increased the yields of all radiolytical products, particularly of formic acid, malonaldehyde and other carboxyl groups. A mechanism of formaldehyde formation is discussed.
