| titleOfInvention | Method for preparing anisaldehyde by microchannel continuous catalytic oxidation of p-methylanisole |
| abstract | The invention discloses a method and a device for preparing anisaldehyde by continuous catalytic oxidation of p-methyl anisole in a microchannel. Methyl anisole glacial acetic acid solution, then add mixed catalyst and initiator to the above solution, stir to prepare a raw material solution; (2) Microchannel catalytic oxidation: feed the prepared raw material solution and oxygen into the microchannel in parallel In the reactor, the reaction temperature is adjusted to be 80-250 ° C, the pressure is 3.0-6.0 MPa, and the residence time is 2-10 min. The reaction solution that has been reacted in the microchannel reactor is cooled and depressurized to normal temperature and pressure, and then collected to anisaldehyde. In the crude product liquid storage tank, the crude anisaldehyde product is obtained, the purity of the crude product is greater than or equal to 85%, and the purity of the anisaldehyde refined product obtained after refining is greater than or equal to 98%; the present invention has high selectivity, fast reaction speed, and short production cycle. And the operation is convenient, the yield is high, the cost is low, and the industrial production is easy. |
