Sulfated La- Zr pillared rectorite solid acids,SO42- /La - Zr- CLR,were prepared by exchanging the Na + hydrate in Na - rectorite with La - Zr pillaring agent and successive introduction of SO42- as accelerator.

• 用镧-锆双组分交联剂交换Na基累托土中的水合钠离子,再引入SO42-作促进剂进行改性,制备了SO42-改性的镧-锆双组分交联累托土固体酸催化剂(SO42-/La-Zr-CLR)。
