The invention discloses a tert-butanol-methanol etherification resin catalyst and a preparation method thereof. The polymer white spheres cross-linked and copolymerized with styrene-divinyl benzene are used as the matrix, the polymer white spheres are placed in a dispersed phase, and then uniform relative polymer white spheres are added. The precursor is wrapped to obtain copolymer white spheres, and the copolymer white spheres are stabilized by functional groups to obtain finished white spheres, and the white spheres are tert-butanol-methanol etherification resin catalysts. The tert-butanol-methanol etherification resin catalyst prepared by the method of the invention has the advantages of high activity, high temperature resistance, high stability, etc.; The adsorption performance of butanol and methanol is high, which makes the two materials more accessible to the active center, easy to react, and the reaction activity is enhanced; the special methanol adsorption capacity of the catalyst reduces the saturated vapor pressure of methanol, improves the utilization rate of methanol, and reduces the Cost of production. |
