| titleOfInvention | A kind of synthetic method of 2,4,6-triphenylpyranyl tetrafluoroborate |
| abstract | The invention discloses a synthesis method of 2,4,6-triphenylpyranyl tetrafluoroborate, which relates to the technical field of photoelectric materials. The invention comprises the following steps: mixing benzaldehyde and acetophenone, stirring, and controlling the reaction The temperature is 15-25°C, add boron trifluoride diethyl ether dropwise to the reaction system, and after the dropwise addition, raise the temperature to 50-80°C and react for 15 hours. When the reaction solution drops to 40°C, pour the reaction solution into the stirring acetic acid In ethyl ester, a yellow solid was precipitated, and after the yellow solid was filtered and purified, 2,4,6-triphenylpyranyl tetrafluoroborate was obtained; the molar ratio of benzaldehyde to acetophenone was 1:3, The mass ratio of boron trifluoride ether to acetophenone is 9:11. The beneficial effect of the present invention is that: the present invention adopts a one-pot method to synthesize 2,4,6-triphenylpyranyl tetrafluoroborate, the synthesis method is simple, the product yield is high, the purity is high, and the industrialization of the product is easy to realize. |
