| | BENZYL ACETOACETATE Usage And Synthesis |
| Chemical Properties | yellow viscous liquid | | Chemical Properties | Benzyl acetoacetate has a sweet, floral, fresh, balsamic, fruity odor similar to that of ethyl acetate. | | Occurrence | Reported found in litchi (Litchi sinensis Sonn.). | | Uses | Benzyl acetoacetate (AAbenzyl) is chemical intermediate used for the syntheses of different organic chemicals Product Data Sheet | | Uses | Benzyl acetoacetate is used as a Pharmaceutical and fine chemical intermediate. | | Preparation | By heating ethyl acetoacetate and benzyl alcohol to 160°C. | | Definition | ChEBI: Benzyl acetoacetate is a carboxylic ester. It is functionally related to a benzyl alcohol. | | General Description | Benzyl acetoacetate undergoes asymmetric bioreduction to form benzyl (S)-(+)-3-hydroxybutyrate in the presence of Candida schatavii strain MY 1831. | | Purification Methods | Fractionate the ester and collect fractions with the expected physical properties. Otherwise add ca 10% by weight of benzyl alcohol and heat in an oil bath (160-170o, open vessel) for 30minutes during which time excess of benzyl alcohol will have distilled off, then fractionate.
