Натрия олеат

Химические свойства

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.

Использование

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

Общее описание

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

Реакции воздуха и воды

Water soluble. Gives basic aqueous solution.

Профиль реактивности

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.

Угроза здоровью

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

Профиль безопасности

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

Методы очистки

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.]
