| titleOfInvention | A kind of green environment-friendly method for synthesizing veratraldehyde |
| abstract | The invention provides a green and environment-friendly method for synthesizing veratraldehyde, which belongs to the technical field of perfume intermediate synthesis, and comprises the following steps: S1, adding vanillin, a methylating reagent and a catalyst to a reaction solvent, and stirring and heat-retaining reaction after heating up; Wherein, the methylating reagent is 1-methoxy-2,2,6,6-tetramethylpiperidine or 1-methoxy-4-hydroxyl-2,2,6,6-tetramethyl Piperidinol, the catalyst includes at least one of oxides, hydroxides, and carbonates of Cs or Ba; S2, after the stirring reaction is completed, wash with deionized water, collect the organic layer, and obtain after steaming the reaction solvent Veratraldehyde; the present invention simplifies the synthesis process, avoids the disadvantages of low production yield, many by-products, difficult separation and the like. |
