use | benzyl butyrate is a edible spice allowed in our country. it is often used to make cheese, cream, apricot, plum, coconut, peach, banana, pineapple, strawberry and other flavor types, as well as rose and wine flavor. the dosage is 310 mg/kg in chewing gum according to normal production requirements. 9.9 mg/kg in baked food; 7.7 mg/kg in candy; 6.9 mg/kg in cold drinks. This product has weak vegetarian and sweet peach flavors, and its aroma is elegant. It is mainly used as a moisturizing agent in vegetarian blend spices, used in soap spices, and also used in food spices, such as peaches, apricots and pears. And other food flavors. Benzyl butyrate is also used as a plasticizer and polymer toughening agent. |
production method | benzyl butyrate is prepared from butyric acid and benzyl alcohol under the catalysis of sulfuric acid: or butyric acid, sodium butyrate and benzyl chloride are mixed and heated to 200 ℃ for 2h in a closed container. Sodium butyrate and benzyl chloride are heated and refluxed in water. After the reaction is over, it is cooled and stratified and distilled under reduced pressure to obtain benzyl butyrate. The finished product is obtained by heating esterification of benzyl alcohol and butyric acid under sulfuric acid catalysis. |
