Porous methyl rhenium trioxide and application method thereof

The invention belongs to the field of synthesis of organic metal compounds, and particularly relates to porous methylrhenium trioxide, which is prepared by the following steps: adding a proper amount of ionic liquid, water and an auxiliary agent into a reaction kettle, uniformly stirring and mixing under the normal pressure condition at 20-40 DEG C, then adding potassium perrhenate into the system, stirring for 1-2 hours, then adding trimethylchlorosilane and tetramethyltin, heating, and reacting for 1-2 hours at the temperature of 20-40 DEG C to obtain the porous methylrhenium trioxide. Controlling the end point by color, properly prolonging the reaction time, cooling, stopping stirring, and after the reaction is finished, filtering, washing, distilling and recrystallizing to obtain porous methylrhenium trioxide; the porous methylrhenium trioxide is applied to alcohol deoxidation and dehydration reaction, and good catalytic activity is shown. The porous rhenium catalyst disclosed by the invention is simple i
