Abstract
Aluminous material is chlorinated in the presence of a reducing agent at pressures greater than three atmospheres. A greater than linear increase in reaction rate obtained at superatmospheric pressures is a feature of the chlorination reaction which is employed to increase aluminum chloride production rate. Choice of pressure used is governed more by mechanical limitations than by an upper limit inherent to the chemical reaction.
