Abstract

The kinetic curves of the desorption of ethyl, n-propyl and n-butyl iodides on red phosphorus at 40, 60 and 100°C were determined. From these and from the rate-of-desorption curves the partition functions were obtained, giving desorption energies and activation energies for the desorption processes. Making use of a radioactive iodine isotope, the differential isotope method was applied to studies of the interaction between alkyl iodides and the surface of red phosphorus. The experimental results seem to indicate that the surface of red phosphorus is heterogeneous, and that, in addition to adsorption, certain chemisorption processes also take place, leading to cleavage of the C-I bond in the molecules of alkyl iodides.
