Abstract: A process for the preparation of a haloalkyldialkylchlorosilane is provided, wherein at the end of a hydrosilylation reaction, the product is recovered and iridium is recovered, the iridium being found in its original form of catalyst or in a converted form, the recovery of the iridium taking place under the following conditions a), b) and c): a) the recovery of the iridium is carried out: 1. either directly on the reaction medium at the end of the reaction, 2. or on the liquid distillation residue, including the byproducts and the iridium or its derivatives, as is obtained after distillation of the reaction medium in order to separate therefrom the product of formula (I), b) the iridium is recovered by bringing the reaction medium or the distillation residue into contact with an effective amount of carbon black which adsorbs the iridium, and c) the carbon black is separated from the iridium for the purpose of recovering the iridium.
