What is ETHYL STEARATE?

Chemical properties

white crystalline mass

Chemical properties

Ethyl octadecanoate is virtually odorless.

Occurrence

Reported found in Jamaican rum, maple syrup, grapefruit juice, guava, grapes, cognac, rum, whiskey, sparkling wine, mustard, beef, cocoa and corn oil.

The Uses of ETHYL STEARATE

A fatty acid ester component of volatile oil from Rhododendron anthopogonoides; shows antimicrobial activity.

What are the applications of Application

Stearic Acid ethyl ester is a saturated fatty acid that perturbs the cell cycle and induces apoptosis

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.

Preparation

By esterification of ethanol with stearic acid.

Production Methods

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.

General Description

Ethyl stearate is a fatty acid ethyl ester (FAEE) is commonly found in vegetable oils.

Purification Methods

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.]
