Abstract1-Octanol is a promising solvent for the extraction of high-level radioactive waste from nuclear fuel reprocessing and a study of radiation effects on 1-octanol is necessary before its industrial application in high-radiation environments In this work, UV-Vis spectroscopy and Fourier transform infrared (FTIR) spectroscopy were used to investigate the radiation stability of 1-octanol in nitrogen for the first time Results indicate that 1-octanol is chemically stable at a dose of 100 kGy and that compounds containing a carboxyl group are formed at a dose of more than 300 kGy The major radiolysis products of irradiated 1-octanol at 600 kGy were analyzed using gas chromatography(GC) and gas chromatography-mass spectrometry(GC-MS) Hydrogen was formed as a major gaseous product and small amounts of carbon dioxide and methane were also found The dominant liquid product was 1-octanal and its mass percent was less than 1% in the 1-octanol solution Small amounts of heptane and 8-pentadecanol were also produced Analysis of the chemical structure and radiolysis products of the irradiated 1-octanol suggests that during gamma irradiation in nitrogen, C-H bond breakage at the alpha-carbon in 1-octanol is the dominant reaction and the C-C bond at the beta-carbon can break as well Additionally, hydrogen abstraction reactions occur between the primary H-atom radical produced during irradiation and 1-octanol
