The stearate esters are prepared by reacting stearic acid with the appropriate Butanol(butyl alcohol)alcohol.
硬脂酸酯是通過使硬脂酸與丁醇反應製備的。硬脂酸酯具有低粘度和油性的獨特性能,在應用於皮膚或嘴唇時會形成不油膩的疏水性薄膜。
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C4H9OH, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, n-BuOH, i-BuOH, and t-BuOH). These are n-butanol, 2 stereoisomers of sec-butanol, isobutanol and tert-butanol. Butanol is primarily used as a solvent, as an intermediate in chemical synthesis, and as a fuel. It is sometimes also called biobutanol when produced biologically and petrobutanol when produced from petroleum; those two names refer to the same substance, but highlight their different origins.
