Influence of the benzyl substituent on radiation chemistry of selected ionic liquids: gaseous products analysis

Gaseous products generated as a result of ammonium, pyrrolidinium and imidazolium ionic liquids (ILs) exposure to ionizing irradiation were under investigations. The main aim was to find out an influence of an aromatic substituent on the radiation chemistry of ILs. Therefore, in each selected ILs groups, an alkyl substituent in an IL cation was replaced by the benzyl one. A presence of the benzyl substituent results in a substantial reduction of radiation yields of generated gases. A relationship between radiation stability of ILs and a quantity of radiolytically generated gaseous products was discussed. (author)
