Abstract
The determination of the kinetics of butadiene dimerization, a second‐order rapid and homogeneous reaction, could be determined in a continuous reactor which was thoroughly stirred in a gas phase by jets from nozzles. The above reaction was studied between 500°C and 600°C by means of a transient method based on the deformation of a concentration pulse signal while crossing the reactor. A study was also made of a modification of the transient method which consisted in superimposing a small pulse to a continuous feed of reactant. The linearization permitted to bring the reaction back to an apparent first order one with respect to the butadiene concentration. The concentration signals were measured by means of a mass spectrometer and stocked in actual time on an IBM 1800 computer. The results found in both cases agreed well with those described in the literature and with those of the conventional method in a steady system. The following expression of the kinetics constant was obtained. \documentclass{article}\pagestyle{empty}\begin{document}$$ \log _{10} k = 11.28 - \frac{{27100}}{{4.575{\rm T}}} $$\end{document}
