Synthesis

Synthetic method

Ammonium myristate is synthesized through neutralization of myristic acid using ammonium hydroxide. The process involves dissolving myristic acid in an alcohol-based solvent, followed by gradual addition of concentrated ammonium hydroxide. The solution is then cooled and allowed to crystallize under controlled conditions to isolate the product. [4]

Industrial method

In commercial production, ammonium myristate is manufactured via large-scale neutralization techniques. Myristic acid is first dissolved in a compatible solvent, and ammonium hydroxide is added incrementally. The resulting mixture undergoes crystallization and subsequent purification steps to achieve high-purity ammonium myristate. [4]

Physical properties

Ammonium myristate forms a white paste. It is soluble in water and ethanol. [5]

X-ray diffraction studies of ammonium myristate show crystals that belong to space group P21/n. [6]

Uses

The compound is used to produce skin care products. [7]

Also used as a cleaning agent, emulsifying agent, and dispersing agent. [5]
