| titleOfInvention | A kind of synthetic method of ethyl isoeugenol |
| abstract | The invention discloses a method for synthesizing ethyl isoeugenol, which belongs to the technical field of synthesis of fine organic chemicals. In the method, eugenol and DEC are used as raw materials, and DEC is fed by steps and dropwise, and ethyl isoeugenol is synthesized by one-step reaction distillation technology under the catalysis of solid alkali and phase transfer catalyst. In the present invention, a relatively environmentally friendly chemical reagent DEC is used to replace the currently used highly toxic and highly corrosive diethyl sulfate as the ethylating reagent, and a solid base and a phase transfer catalyst catalytic system are selected through the step-by-step and dropwise addition methods. , One-step method to synthesize ethyl isoeugenol, changing the current synthesis process of two-step reaction of eugenol isomerization and ethylation, and the one-time feeding method of DEC. This is a relatively green synthesis route, and the synthesis route is short, the reaction time is short, the product yield is high, energy saving, consumption reduction, and has a good industrial application prospect. |
