Process for continuously preparing methylaluminoxane

The invention discloses a process for continuously preparing methylaluminoxane, and relates to the technical field of chemical production. In view of the problems of complicated operation steps, poorsafety controllability, large hazardous waste amount and high product quality controllability difficulty of the existing intermittent preparation process, the following scheme is provided, namely, themethod comprises the following steps of: S1, preparing a micro-tube reactor, an efficient mixer, a micro water metering pump, a micro solvent metering pump, a micro trimethylaluminum solution metering pump, a pure water storage tank, a solvent storage tank, a trimethylaluminum solution tank and a collecting tank; and S2, mixing water and an inert solvent through the efficient mixer to form an emulsion, enabling the emulsion to quickly enter the micro-tube reactor through a pipeline to quickly react with a trimethylaluminum solution to produce methylaluminoxane, and enabling the product to enter the collecting tank.
