Description
The reaction of isotope exchange betweeen [3-(iodophenyl)methyl]guanidine, mIBG, and [131I]-iodide in relatively concentrated solutions, in the presence of different ammonium salts, in a closed system, over the temperature range from 130 to 150 C deg, has been investigated. The reaction occurs either with (NH4)2SO4 or CH3COOH, which indicates that the reaction goes through some intermediate stages. Kinetic studies show the influence of the additives. The activation energies for the reaction with (NH4)2SO4/H2O, (NH4)2SO4/CH3COOH and CH3COOH are 121.1, 115.1 and 84.5 kJ * mol-1, respectively. (author) 15 refs.; 5 figs.; 1 tab
