Example Embodiment
[0021] The technical content of the patent application will be described in detail below through various embodiments, but the protection scope of the patent application is not limited to the content described in the embodiments. The catalyst used in the preparation process of ethyl tert-butyl ether etherification is made of p-tert-butyl styrene and divinyl benzene monomers, suspended and copolymerized under the action of porogen and surfactant, to obtain white copolymer balls, which are passed through the pores. Obtained by purification and sulfonation.
[0022] Catalyst C-1
[0023] In a stainless steel stirred tank equipped with reflux condensing device, add 2000g of water and surfactants, heat and stir to completely dissolve to obtain the water phase. When the temperature of the stainless steel stirred tank is raised to 60℃, add the oil phase of the mixed organic phase. The temperature is 80℃, the stirring speed is 60r / min, and the polymerization reaction is 8 hours to obtain t...
