Sodium oleate Usage And Synthesis

Chemical Properties

Sodium oleate is a white solid with a mild odor resembling tallow. It is capable of dissolving in water but may undergo partial decomposition in the process. In addition, it is soluble in alcohol and can produce froth or foam when shaken with a water solution (soap). Sodium oleate is produced by reaction of NaOH and oleic acid (in alcoholic solution) and evaporating. It can be used as a source of oleate.

Uses

Sodium Oleate is the sodium salt of oleic acid. it functions as a binder, emulsifier, and anticaking agent.

Uses

preparation of Turkey red oil, soft soap and other oleates; in polishing Compounds; waterproofing textiles, oiling wool; manufacture of driers; thickening lubricating oils. Pharmaceutic aid (solvent). The barium salt in rodent extermination.

Uses

sodium oleate is a mild cleansing and foaming agent generally used in soaps. It is derived from natural fats and oils.

Definition

ChEBI: Sodium oleate is an organic molecular entity.

General Description

Light tan solid with a slight tallow-like odor. Sinks and mixes slowly with water.

Air & Water Reactions

Water soluble. Gives basic aqueous solution.

Reactivity Profile

Salts, basic, such as SODIUM OLEATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Health Hazard

Inhalation of dust causes irritation of nose and throat, coughing, and sneezing. Ingestion causes mild irritation of mouth. Contact with eyes causes irritation.

Biochem/physiol Actions

Oleic acid increases hepatic secretion of apolipoprotein B100 in hepatocyte cell lines and in mice . Oleic acid inhibits apolipoprotein B100 secretion at higher physiologic doses .

Safety Profile

Poison by intravenous route. Migrates to food from packaging materials. Combustible when exposed to heat or flame. When heated to decomposition it emits toxic fumes of Na2O

Purification Methods

It crystallises from EtOH and is dried in an oven at 100o. [Beilstein 2 H 465, 2 I 201, 2 II 434, 2 III 1405, 2 IV 1645.]
