Batch reactor experiments were performed to measure the rate of the reaction 1.5 kaolinite + K{sup +} = muscovite + H{sup +} + 1.5 water at temperatures ranging from 250 to 307{degree}C. In these experiments, the rate of kaolinite conversion to muscovite/illite was monitored as the rate of production of H{sup +}. Runs were performed in small volume (50 mL) titanium hydrothermal reactors charged with well-crystallized Georgia kaolinite, Indian Ruby muscovite, and 25 mL of KCl solution (0.5-2.0 m). Both solids and solutions were monitored at specific intervals throughout each experiment.
