•The butanal oxime consumption yield has been determined by GC–MS in aqueous media.•Enhancement of the hydrogen production is observed in the presence of butanal oxime.•Diminution of the H2O2 production is observed in the presence of butanal oxime.•Butanal oxime reaction with H∙/HO∙ by hydrogen abstraction mechanism is discussed.
Samples of butanal oxime in aqueous solution have been irradiated with the helion (4He2+) beam of the ARRONAX (Nantes) and the CEMHTI (Orléans) cyclotrons. The consumption yield of butanal oxime has been measured by gas-chromatography coupled with mass spectrometry. Yields of gaseous products (mainly H2) have also been measured by micro-gas-chromatography. Butanal oxime can react with H∙ radicals by abstraction mechanism to enhance H2 production. Yields of liquid phase products (hydrogen peroxide and nitrite ion) have been measured by colorimetric methods. Butanal oxime acts as a scavenger of OH∙ radical to inhibit the production of H2O2. The observation of the radiolytic products allows then to discuss a degradation mechanism of butanal oxime in aqueous solutions.
