Aluminum chloride-charcoal catalyst

Aluminum chloride. Isomerization did not take place when 7i-butane was treated with aluminum chloride-charcoal catalyst alone. However, in the presence of a quantity of air such that the concentration of oxygen was approximately 0.01-0.02 moles oxygen per 100 moles n-butane introduced, isomerization to isobutane took place. The experimental data are given in Table VIII. 

The transformation takes place in the gas phase, in the presence of a supported mercuric chloride base catalyst in general, at a temperature between 100 and 170°C, and a pressure of about 03.106 Pa absolute. The support is activated charcoal, but this can be replaced by graphite, aluminum and sodium silicate etc.
