스테아린산뷰틸 C화학적 특성, 용도, 생산
화학적 성질
Butyl stearate is a colorless or pale yellow oily liquid or low melting waxy solid. It has no odor or a faintly fatty odor. soluble in acetone, chloroform, soluble in ethanol, insoluble in water.출처
Reported found in fresh apple and boiled mutton.용도
butyl stearate is a stearic acid used in very small quantities in cosmetic preparations as an emulsifier for creams and lotions. It has been shown to cause allergic reactions.제조 방법
Butyl stearate is obtained by esterification of stearic acid and butanol, dealcoholization, washing with water and pressure filtration.By reacting silver state with n-butyl iodide at 100°C by transesterification of glyceryl tristearate (tristearin) with n-butyl alcohol.
정의
ChEBI: Butyl octadecanoate is a fatty acid ester that is the butyl ester of stearic acid. It has a role as an algal metabolite. It derives from an octadecanoic acid.일반 설명
Butyl stearate is a fatty acid ester, which has application in cosmetics, personal care products, and as an emollient in food industries.Purification Methods
Acidic impurities are removed by shaking with 0.05M NaOH or a 2% NaHCO3 solution, followed by several water washes, then purified by fractional freezing of the melt and fractional crystallisation from solvents with boiling points below 100o. [Beilstein 2 IV 1219.]스테아린산뷰틸 준비 용품 및 원자재
