製造方法
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.
定義
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.
一般的な説明

純化方法
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.]
