Abstract

The kinetics of a fundamental reaction of the aluminum subhalide process, 2Al(l)+AlCl₃(g)=3AlCl(g), was studied by the flow method under a reduced pressure of trichloride at 900∼1100°C.<BR>The reaction rate increased with the increase in the flow rate of trichloride, namely its pressure. As a result of the present experiment, the reaction rate was expressed by the following equation:<BR>V=1.28P_AlCl<SUB>3</SUB>^4⁄3e^{−11800⁄RT} (Al g/cm²·min).<BR>The apparent activation energy of this reaction was 11.8 kcal/mol. The reaction ratio of AlCl₃ increased with rising temperature and lowering trichloride pressure.
