Method for preparing polymetal carbosilane from liquid polycarbosilane and application of polymetal carbosilane
The invention provides a method for preparing polymetallo-carbosilane by using liquid polycarbosilane and application, and the method comprises the following steps: preparing polymetallo-carbosilane: adding liquid polycarbosilane and metallocene into a reaction kettle in proportion, heating to 300-500 DEG C under the protection of high-purity inert gas, carrying out heat preservation reaction, and cooling to room temperature after the reaction is finished; fine treatment of the product: dissolving the obtained solid product into an organic solvent, filtering to remove a small amount of precipitate in the solution to obtain a solution G, and removing the solvent in the solution G to obtain the product polymetal carbosilane; the polymetal carbosilane composite carbide can be prepared after further heat treatment. The method has the advantages that the content of metal elements in polymetallocarbosilane is adjustable, the reaction steps are simple, the reaction process is mild and controllable, the preparation cost is low, and the method is suitable for industrial production.
本发明提供一种利用液态聚碳硅烷制备聚金属碳硅烷的方法与应用，包括如下步骤：聚金属碳硅烷制备：将液态聚碳硅烷与茂金属按比例投入反应釜中，在高纯惰性气体保护下，升温至300‑500℃，保温反应，反应结束后冷却至室温；产物精处理：将所得固体产物溶入有机溶剂中，过滤脱除溶液中的少量沉淀物后得到溶液G，将溶液G中的溶剂脱除，即得到产品聚金属碳硅烷；可以进一步热处理后，制备聚金属碳硅烷复合碳化物。本发明具有聚金属碳硅烷中金属元素含量可调、反应步骤简单、反应过程温和可控、制备成本低、适用于工业化生产等优点。
