The method is that salicylic acid and isoamylol are in SO 4 2‑ /TiO 2 ‑SiO 2 The isoamyl salicylate is synthesized under the catalysis of a super acid catalyst. In the preparation process of the catalyst used in the invention, isopropanol is added to effectively adjust the hydrolysis rate of titanium isopropoxide as a Ti salt precursor, so that Ti is realizedMetal on SiO 2 The high dispersion improves the utilization rate of Ti metal, and in addition, compared with the conventional super acidic catalyst, SiO 2 The doping of the catalyst not only increases the B acid position of the catalyst, further improves the acidity of the catalyst, but also improves the stability of the catalyst, thereby prolonging the service life of the catalyst. The catalyst used in the method can be separated and recycled through filtration, the problem that a large amount of waste acid and solid waste are generated after the common organic acid catalyst is used is solved, and the three-waste treatment cost is greatly reduced.)
