Zusammenfassung: | The invention discloses a preparation method of an organosilicon monomer synthesis reaction copper catalyst. The preparation method comprises the following steps: smelting copper and zinc, and atomizing to prepare powder to obtain powder A; the copper oxide powder is subjected to incomplete roasting, and powder B is obtained; and mixing the powder A and the powder B, reacting at the temperature of 450-600 DEG C, and ball-milling and sieving the material obtained after the reaction to obtain the copper catalyst. The catalyst prepared by the method disclosed by the invention can well form an active contact with silicon powder in the synthesis of an organic silicon monomer, so that high reaction activity can be kept in the synthesis reaction for a long time. The generation of side reactions such as high-boiling-point substances is reduced, and the selectivity of dimethyl dichlorosilane is improved. Meanwhile, the service life of the catalyst is longer, the production cost is effectively reduced, and economic ben |
