The invention discloses a method for synthesizing tricyclodecene methyl ether. The tricyclodecene methyl ether is prepared by the following steps: dicyclopentadiene is taken as a raw material and reacts with methanol in the presence of a catalyst; and solid acid is taken as the catalyst, the reaction time is between 2 and 5 hours, and the reaction temperature is between 50 and 80 DEG C. The method takes the solid acid as the catalyst when a product is synthesized, avoids the serious three-waste problem caused by using sulfuric acid as the catalyst, and has easy operation, quick reaction rate and high reaction yield.
Description
technical field [0001] The present invention relates to the synthesis method of tricyclodecenyl methyl ether. Background technique [0002] Tricyclodecenyl Methyl Ether has a strong green, fruity and herbal fragrance, and the fragrance is transparent. It is an excellent flavor enhancer in lavender and herbal essences. The current synthesis method of tricyclodecenyl methyl ether is easy to pollute the environment, has slow reaction speed and low reaction yield. Contents of the invention [0003] Aiming at the above problems, the present invention provides a method for synthesizing tricyclodecenyl methyl ether which is easy to operate, fast in reaction speed and high in reaction yield. [0004] The synthesis method of tricyclodecenyl methyl ether of the present invention: take dicyclopentadiene as raw material, dicyclopentadiene as raw material, take solid acid as catalyst and react with methanol to prepare. Its reaction formula is as follows: [0005] [0006] The adv...
