Conclusions
-
1.
The prior chlorination of silicon leads to a reduction in the start of the reaction of silicon with methyl chloride by ∼300°.
-
2.
The reaction of the chlorinated silicon with methyl chloride leads to a loss in the activity of the silicon surface, which is explained by the consumption of the intermediate products that are formed on the silicon surface during chlorination. A second chlorination of the silicon restores the activity.
