Chemical Properties
Sodium oleate, also known as oleic acid sodium or 143-19-1, 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.
General Description
Light tan solid with a slight tallow-like odor. Sinks and mixes slowly with water.
Reactivity Profile
Salts, basic, such as OLEIC ACID, [SODIUM SALT], 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.
Air & Water Reactions
Water soluble. Gives basic aqueous solution.
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.
