| titleOfInvention | Solid acid catalyst for preparing acetal/ketone and preparation method and application thereof |
| abstract | The invention relates to a modified cyclodextrin loaded solid acid catalyst and application thereof in preparing acetal/ketone, wherein the modified cyclodextrin is polyethyleneimine modified carboxymethyl-beta-cyclodextrin; the solid acid is selected from SO 4 2‑ /ZrO 2 、CH 3 COO ‑ /ZrO 2 、CH 3 SO 3 ‑ /ZrO 2 (ii) a In the catalyst, the mass ratio of the modified cyclodextrin to the solid acid is 1 (0.1-10). The method for preparing the acetal/ketone comprises the step of carrying out condensation reaction on aldehyde/ketone and alcohol serving as starting materials by using the catalyst disclosed by the invention to prepare the acetal/ketone. The method has the characteristics of high selectivity and recyclable unreacted raw materials and catalyst. In the invention, other water absorbents are not added, other solvents are not used, byproducts are hardly generated, and the method has high selectivity and is a novel green and environment-friendly method for synthesizing the acetal and the ketal. |
