In the presence of iron(III) or other oxidants, aqueous acid chloride solutions of RhCl5(H2O)2− catalyze under mild conditions the oxidation of ethylene to acetaldehyde. The kinetics of the reaction measured by gas-uptake techniques indicate the presence of both ethylene dependent and independent paths. Besides fully protonated anions, hydroxy species such as RhCl5 (OH)3− and RhCl4(OH)(H2O)2−, although present in very small concentrations, are significantly reactive towards ethylene. A mechanism, based on that postulated for a similar palladium(II) system in the well-known Wacker process, is presented. Under our reaction conditions the slow steps in the rhodium system involve formation of π-complexes in the ethylene dependent paths and the formation of tetrachlororhodate(III) complexes in the ethylene independent paths. Iron(III) regenerates the rhodium(III) catalyst by oxidation of the rhodium(I). Rate constants are estimated for the various reaction paths.

Aniline Polymerization

The reaction kinetics of the chemical polymerization of aniline in aqueous acid solutions with FeCl3 as the oxidant (initiator) was investigated at 25?C. The polymerization was performed in a special reactor which enabled the initial concentration of oxidant to be kept constant during the polymerization reaction. The order of the reaction of ANI polymerization with respect to FeCl3 was calculated as n=0.18. The rate constant k of the polymerization reaction was found to be 9.1x10-5(mol dm-3)-1,18 s-1. The theoretical yield of the reaction was calculated using the Faraday law and the experimentally determined quantity of electricity exchanged during the polymerization reaction. There was a discrepancy between the experimentally and theoretically determined yield, indicating that the oxidant was being consumed in some side reactions, which is an accordance with the fact that the order of the reaction of ANI polymerization with respect to FeCl3 is a non-integer number.
