Chemische Eigenschaften
Ethyl octadecanoate is virtually odorless.
Chemische Eigenschaften
white crystalline mass
Occurrence
Reported found in Jamaican rum, maple syrup, grapefruit juice, guava, grapes, cognac, rum, whiskey, sparkling wine, mustard, beef, cocoa and corn oil.
Verwenden
A fatty acid ester component of volatile oil from Rhododendron anthopogonoides; shows antimicrobial activity.
Ethyl stearate is occasionally used in flavor compositions where a waxy taste (or mouthfeel) is desirable, e.g. in imitation Honey or in certain types of chocolate flavor.
synthetische
By esterification of ethanol with stearic acid.
Definition
ChEBI: A long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of stearic acid with the hydroxy group of ethanol.
Vorbereitung Methode
Ethyl stearate can be produced by esterification of Ethanol with Stearic acid. The acid is obtained from Oleic acid by hydrogenation, a method which yields comparatively pure Stearic acid, free from Palmitic acid.
Allgemeine Beschreibung
Ethyl stearate is a fatty acid ethyl ester (FAEE) is commonly found in vegetable oils.
läuterung methode
The solid portion is separated from the partially solid starting material, then crystallised twice from EtOH, dried by azeotropic distillation with *benzene, and fractionally distilled through a spinning-band column at low pressure [Welsh Trans Faraday Soc 55 52 1959]. [Beilstein 2 IV 1218.]
