Abstract
The synthesis of vanitrope from eugenol is carried out by two steps of reaction,ethylation and demethylation and the reaction conditions are studied. In the process of ethylation, diethyl sulfate is used and certain amount of Bu_4N~+Br~- is added as catalyst and the reaction temperature is reduced to 160℃. The yield of the product reaches 85.5%. In demethylation process, LiI is used as reagent , the selectivity of the reaction is raised and the reaction is promoted.
