Daily essence: It is used to make rose, jasmine, lily, lily and other floral essence, and can also be used as the spice of soap. Other uses: Used in small quantities as plasticizers or polymer toughening agents =============================================================================== Regarding the synthesis route of benzyl butyrate, public information mentions its main chemical synthesis methods, usually involving esterification reactions. The following are synthetic pathways based on common chemical knowledge: Esterification reaction: The most classic synthesis method for benzyl butyrate is the direct esterification reaction between butyric acid and benzyl alcohol under acidic catalyst (such as concentrated sulfuric acid). In the reaction, the carboxyl group of butyric acid dehydrates and condenses with the hydroxyl group of benzyl alcohol to form an ester bond, producing benzyl butyrate and water. CH₃CH₂CH₂COOH + C₆H₅CH₂OH → CH₃CH₂CH₂COOCH₂C₆H₅ + H₂O Other possible synthetic pathways: In addition to direct esterification, other methods may also be used in industry, such as: Reaction of Butynyl chloride with benzyl alcohol: By using Butynyl chloride, which has higher reactivity, to react with benzyl alcohol under alkaline conditions, the target product can be generated more quickly. Ester exchange reaction: ester exchange between methyl or ethyl butyrate and benzyl alcohol in the presence of a catalyst is also a feasible industrial route.
