Solid acid catalyst for synthesizing 2-propyl-1,3-dioxocyclo-5-pentene and preparation method thereof and method for using solid acid catalyst to synthesize 2-propyl-1,3-dioxocyclo-5-pentene

The invention discloses a solid acid catalyst for synthesizing 2-propyl-1,3-dioxocyclo-5-pentene. A sulfonic acid group is grafted on the surface of a carrier silicon dioxide, and the preparation method of the solid acid catalyst comprises the steps that an organosilicone coupling agent containing a mercapto group is grafted to a carrier material loading silicon dioxide by adopting a post graftingmethod, and then the solid acid catalyst is prepared through the processes of oxidation, acidification and the like. The method for using the solid acid catalyst to synthesize the 2-propyl-1,3-dioxocyclo-5-pentene comprises the steps that the solid acid catalyst reacts with 1, 4-butylene glycol, n-butanal and a water-carrying agent, heating is conducted till no water is generated in the water diversion backflowing process, filtering and reduced pressure distillation are conducted, cut fraction under the vacuum degree of -0.098MPa and at the boiling point of 100-120 DEG C is collected, and theproduct 2-propyl-1,3-dioxocyclo-5-pentene is obtained. The provided solid acid catalyst has the advantage that equipment is not corroded, no waste water is drained out, the cost is low, the yield ishigh, and the catalyst is liable to being recycled and used repeatedly.
