LOW MELTING SOLID OR LIQUID | [Occurrence]
Reported found in fresh apple and boiled mutton. | [Definition]
ChEBI: A fatty acid ester that is the butyl ester of stearic acid. | [Preparation]
By reacting silver state with n-butyl iodide at 100°C by transesterification of glyceryl tristearate (tristearin) with n-butyl alcohol. | [General Description]
Butyl stearate is a fatty acid ester, which has application in cosmetics, personal care products, and as an emollient in food industries. | [Materials Uses]
Butyl stearate as candle material: Besides the synthetic paraffins mentioned, other substances,
individually or in combinations, may also have been added to the candle
base material. These are in particular poly-alpha-olefins, low-melting
point paraffin fractions and products which have been obtained from
naturally occurring fats and oils and have been prepared by a chemical
modification process, such as for example butyl stearate. | [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.] |
