| Introduction | anisole acetate is the acetate of 4-methoxybenzyl alcohol, which is a natural flavor, found in a variety of fruits and herbs. It is also used as a flavoring agent to produce a variety of flavors. |
| preparation | anisyl acetate can be prepared by esterification of 4-methoxybenzyl alcohol with acetic acid. |
| assay | was determined by method one in the ester determination method (OT-18). The amount of the sample was 1.5g. The equivalence factor (e) in the calculation is taken as 90.11. |
| toxicity | GRAS(FEMA). |
| usage limit | FEMA(mg/kg): Soft drink 6.3; Cold drink 8.0; Candy 15; Baked goods 12; 11; Pectin sugar 30. Moderate limits (FDA § 172.515,2000). |
| Use | GB 2760-1996 specifies the permitted use of flavorants. Mainly used in the preparation of artificial cinnamon oil and berries, strawberries, vanilla, cocoa, chocolate, vanilla beans and other flavors. It is used for Acacia, shaming flower, Violet, Robinia pseudoacacia, Magnolia, clove, Lonicera japonica, Hawthorn flower, new Humulus scandens and other fragrance types for its green and sweet flowers. In coordination with bean flavor, it can set off powder flavor. In combination with rabbit ear aldehyde, an unusual, potent, pleasant aroma is produced. It can be used for berries, chocolate, cocoa, cherry, vanilla beans and other edible, wine flavor. it can be used for the blending of almond, floral fragrance and coconut flavor. |
| production method | a mixture of anisole and formaldehyde is saturated with hydrogen chloride at 0 °c and washed several times in ice water, after the reaction was completed, the acetic acid was removed by distillation. The residue was washed with water and sodium carbonate solution, and purified by distillation under reduced pressure. It is obtained from the reaction of p-methoxybenzyl alcohol (anisol) with acetic anhydride. |
