The pyrolysis of n-butane

A study of the pyrolysis of n-butane was carried out using an all-gold tubular reactor. The initial rate of decomposition of the n-butane was of 1.50-order with respect to the partial pressure of the n-butane. A free radical mechanism, similar to that originally proposed by Rice, accounted satisfactorily for the distribution of products. Oxygen was rigorously excluded from the pyrolysis gases. The surfaces of the gold reactor had been acid-treated to remove oxide impurities. Some preliminary experiments were performed in the partial oxidation of n-butane.
