화학적 성질
white fine crystalline powder or needles용도
Cholesteryl acetate is used in cosmetics, wrist watches, thermometers, propane tank volume indicators, video displays, pharmaceuticals.정의
ChEBI: Cholesteryl acetate is a cholesterol ester obtained by formal acylation of the hydroxy group of cholesterol by acetic acid. It has a role as a human metabolite. It is a cholesteryl ester and an acetate ester.제조 방법
Cholesteryl acetate can be synthesized by the reaction of cholesterol with acetic anhydride in the presence of a catalyst such as pyridine or sulfuric acid. The reaction proceeds as follows:Cholesterol + Acetic anhydride → Cholesteryl acetate + Acetic acid
The reaction is typically carried out at room temperature or slightly elevated temperatures for several hours. The resulting cholesteryl acetate can be purified by recrystallization from a suitable solvent such as ethanol or acetone.
Purification Methods
Crystallise the acetate from n-pentanol or Me2CO. Also purify it by chromatography through silica gel and eluting with MeOH. [Beilstein 6 III 2607, 6 IV 4004.]클로에스테롤 아세트산 준비 용품 및 원자재
