| titleOfInvention | Roasted hydrotalcite catalyst with magnetic core, preparation and application in toluene side chain formaldehyde alkylation reaction |
| abstract | A calcined hydrotalcite catalyst with magnetic core, its preparation and its application in toluene side chain formaldehyde alkylation reaction belong to the technical field of magnetic catalyst and petrochemical industry. In the presence of magnetic Fe 3 O 4 A layer of mesoporous SiO is rapidly formed on the surface of the core 2 Shell layer of SiO 2 @Fe 3 O 4 Nanospheres. Then using magnetic SiO 2 @Fe 3 O 4 The nanospheres are taken as cores, and magnetic SiO is subjected to ultrasonic treatment, urea ultra-uniform precipitation, hydrothermal crystallization and the like 2 @Fe 3 O 4 In-situ synthesizing LDHs @ SiO with different Mg/Al ratios and LDHs shell layers on the surfaces of the nanospheres 2 @Fe 3 O 4 The material is roasted to prepare a series of novel magnetic LDO @ SiO with magnetic cores and LDO shell layers 2 @Fe 3 O 4 Acid-base bifunctional catalyst. Used for the catalytic reaction of generating styrene by alkylating toluene side chain formaldehyde. |
