RADIATION YIELD OF STABLE RADIOLYSIS PRODUCTS OF 1-CHLOROBUTANE, 1-CHLOROBUTENE-2, 1-CHLOROPROPANE, 2-CHLOROPROPANE AND 1,3-DICHLOROPROPANEGAMMA-IRRADIATED IN AN OXYGEN-FREE ATMOSPHERE

The stable radiolysis products of 1-chlorobutane (1-CB), 1-chlorobuten e-2 (1-CB-2), 1-chloropropane (1-CP), 2-chloropropane (2-CP) and 1,3-d ichloropropane (1,3-DCP) gamma-irradiated in an oxygen-free atmosphere have been investigated. The pure radiolysis products were separated b y preparative gas chromatography and identified by NMR and mass spectr oscopy as well as qualitative gas chromatography. The compounds formed were determined by potentiometric analysis and quantitative gas chrom atography. From 1-CB we have obtained in the gas phase: HCl, H-2, buta ne; in the liquid phase: 2-chlorobutane, 1,3-dichlorobutane and a mixt ure of oligomers of the initial compound (dimer and trimer). We have n ot recorded H-2 in 1-CB-2. The main gaseous products of radiolysis of 1-CP are HCl and H-2. Radiation yield of isomerization was determined. From 2-CP we have obtained in the gas phase: HCl and H-2; in the liqu id phase: 2,2-dichloropropane and a mixture of oligomers of the initia l compound (dimers and trimers). From 1,3-DCP we have found in the gas phase: HCl and H-2, in the liquid phase: 1-CP, 2-CP, 1,2-DCP and olig omers. Preliminary schemes for the formation of stable products are pr oposed.
