Synthesis method

1. It is produced by direct esterification of phenol and acetic anhydride.

2. By �Cresol reacts with acetic anhydride in the presence of a small amount of sulfuric acid: after the reaction, it is washed with water and distilled to obtain the finished product.


1. Suitable for narcissus, narcissus and large-flowered jasmine scents. It is also suitable for white orchid, lilac, lily of the valley, hyacinth, vanilla, and ylang-ylang. It has the effect of increasing the rich floral aroma. The dosage is generally less than 1%. It is sometimes used in nutty and nutty flavors in food flavors. middle.

2. Blending spices, blending ylang ylang, narcissus, cananga ylang, honeysuckle and other flavors. It has sufficient effect at concentrations below 1%. A small amount is used for food flavor.

3.GB 2760-96 stipulates that edible spices are allowed to be used. Mainly used for preparing banana, cherry, nut and mixed fruit flavors.

4. Used as flavoring agent

5. Used in baked goods and frozen dairy products.
