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 tricyclohexyl tin derivatives which are valuable herbicides. |
