아세토아세트산벤질에스테르 C화학적 특성, 용도, 생산
화학적 성질
Benzyl acetoacetate has a sweet, floral, fresh, balsamic, fruity odor similar to that of ethyl acetate.출처
Reported found in litchi (Litchi sinensis Sonn.).용도
Benzyl acetoacetate (AAbenzyl) is chemical intermediate used for the syntheses of different organic chemicals Product Data Sheet제조 방법
By heating ethyl acetoacetate and benzyl alcohol to 160°C.일반 설명
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.
