Kinetics of Oxidation of 1-Butene with Palladium(II) Chloride in Stirred Vessel with a Flat Gas-Liquid Interface

Abstract

The oxidation of 1, -butene known in industry as Wacker-process was studied from the standpoint of the chemical absorption theory.
The experiment was carried out in a stirred vessel with a flat gas liquid interface at 35° C in the diffusion control region.
The observed chemical absorption rates of 1-butene were analyzed on the, Joa. sis of the chemical absorption theory of m-th order irreversible reaction, and carbonylation reaction was found to be first-order with respect to 1-butene or palladous chloride, to be reciprocal to -firstorder to chloride ion and to be zero-order to hydrogen ion.
Then, the mechanism of the transformation of 1-butene alladous-π-complex to a-complex was assumed that r-complex was attacked directly by the hydrotcy group to form a-complex.
