| titleOfInvention | A kind of method for preparing concentrated vanillin from sassafras oil |
| abstract | The invention discloses a method for preparing concentrated vanillin from sassafras oil. The sassafras oil is used as a raw material, the amount of KOH and methanol is adjusted when the safrole is ring-opened and isomerized, and the ring-opening method is carried out by distilling methanol with water. , the reaction is milder and controllable, and the ring-opening product is not acidified, and then directly ethylated with diethyl sulfate, the reaction temperature is greatly reduced, the process is simple, and the yield is high; Phenol, synthesizing ethyl vanillin through oxidation reaction, not only reduces the treatment process and cost of the by-product, but also further reduces the cost of the by-product ethyl vanillin, which is an ideal industrialized preparation method Lansing's route. |
