Thermal Reaction of Methyl Oleate in the Presence of Iodine

On the Rate Equation of Geometrical Isomerization

Abstract

Iodine-methyl oleate-heptane solutions were heated in sealed tubes at 140°C.
It was found that experimental data satisfy the following rate equation :
-d [C] /dt=k_cis [C] -k_trans [T] /√1+K_cis [C] +K_trans [T] k_cis= (const) × [I₂] ^1/2, k_trans= (const) '× [I₂] ^1/2
where [C] and [T] are the concentrations of cis and trans isomers, respectively. K_cis and K_trans denote the iodine molecule-corresponding isomer charge transfer equilibrium constants.
