| titleOfInvention | Synthetic method and application of magnetic solid acid catalyst |
| abstract | A synthetic method of a magnetic solid acid catalyst and application thereof belong to the technical field of catalyst preparation. The invention adds Tween-80 aqueous solution and FeSO into a reaction vessel 4 ·7H 2 O, adding hydrazine hydrate after heating in water bath, reacting at constant temperature, and then performing centrifugal separation to obtain nano Fe 3 O 4 (ii) a Modifying the Fe-Fe alloy by using sodium citrate to obtain Fe 3 O 4 A magnetic fluid; mixing Fe 3 O 4 Magnetic fluid, ZrOCl 2 ·8H 2 Adding O and tetrabutyl titanate into a mixed solution of water and ethanol, heating, quickly stirring, dropwise adding ammonia water, standing at low temperature for aging, and washing with water until no Cl is formed ‑ Filtering and drying in a drying oven; the final magnetic solid acid catalyst was obtained after work-up. The magnetic solid acid catalyst has high catalytic efficiency, generates no waste liquid compared with the traditional inorganic acid catalyst, better accords with the green chemical concept, can repeatedly recover and use by utilizing the magnetism, has small activity loss, and is suitable for industrial production and hopeful to replace the traditional petroleum polyol as the raw material for synthesizing polyurethane. |
