ABSTRACT OF THE DISCLOSURE
A process and apparatus for the continuous production
of cyclohexyl magnesium halide. Cyclohexyl halide is fed at a
constant rate into a thermostatized column from the bottom thereof,
the column containing magnesium shavings fed from the top thereof,
and the desired cyclohexyl magnesium halide is recovered from the
top of the column. According to the invention, there is no
need to carry out the reaction in an inert gas atmosphere, such as
always required in known discontinuous processes. The invention
has the further advantage of enabling one to obtain a complete
reaction with a single passage of the halide into the column,
without having to resort to recycles, since the path followed
by the magnesium allows the same to reach the reaction area in
conditions of maximum reactivity. Cyclohexyl magnesium halides
are products particularly useful in the production of tricyclo-
hexyl tin derivatives which are valuable herbicides.
