Radiation-induced Addition Reaction of Sodium Hydrogensulfite to Allyl Alcohol in Aqueous Solution

Abstract

Addition reaction of sodium hydrogensulfite to allyl alcohol was initiated by γ -rays in an aqueous sodium sulfite buffered solution. The rate of disappearance of sodium hydrogensulfite, which is equal to that of allyl alcohol, is proportional to the concentration of hydrogensulfite ion and varies inversely with the concentration of allyl alcohol. Chain termination reaction was deduced as follows: HOCH₂CHCH₂SO₃^- + CH₂=CHCH₂OH → HOCH₂CH₂CH₂SO₃^- + CH₂=CHCHOH The apparent rate constant of sodium hydrogensulfite consumption was calculated to be 1.28x10^-5 exp (1.66 x 10³/RT) mol/l· sec at a dose rate of 6.4 0x 10¹⁵ eV/g· sec.
