| titleOfInvention | Direct method for synthesising alkylhalogenosilanes |
| abstract | Process for the preparation of alkylhalosilanes by reaction of an alkyl halide, preferably CH 3 Cl, with a solid body, referred to as contact body, formed of silicon and of a catalytic system comprising (α) a copper catalyst and (β) a group of promoting additives comprising:n an additive β1 chosen from metallic zinc, a zinc-based compound and a mixture of these entities, an additive β2 chosen from tin, a tin-based compound and a mixture of these entities, optionally an additive β3 chosen from cesium, potassium, rubidium, a compound derived from these metals and a mixture of these entities, said direct synthesis process being characterized by the following points, taken in combination:n the copper catalyst (α) is in the form of metallic copper. of a copper halide or of a mixture of these entities, the contact body additionally includes a supplementary promoting additive β4 chosen from a derivative of an acid of phosphorus and a mixture of these entities. |
