Ammonium laurate is a chemical compound with the chemical formula NH₄C₆H₇O₆.This is an organic ammonium salt of lauric acid. ^[3]

Synthesis

Ammonium laurate can be prepared by mixing dry ammonia with an aqueous solution of pure lauric acid. ^[1] This industrial method requires introducing ammonia gas into a lauric acid solution dissolved in a non-water-based solvent. The process is conducted under carefully regulated temperature and pressure parameters to maximize both the quantity and quality of the resulting product.

Also, ammonium laurate can be obtained by reacting lauric acid with ammonium hydroxide. This process generally begins with dissolving lauric acid in a solvent like ethanol, followed by the addition of ammonium hydroxide to the mixture. ^[4]

Physical properties

The compound typically appears as a white to off-white solid or powder. It is soluble in water, making it useful in various applications. ^[5]

The substance is harmful when inhaled, ingested, or put in contact with the skin. It can cause skin irritation and eye damage. It can emit harmful fumes under fire conditions.

Uses

The compound is used as a surfactant, wetting agent, emulsifier with foaming properties. ^{[6] [7]}

Also, ammonium laurate is used in the extraction and recovery of polyhydroxyalkanoates (PHAs), biodegradable polymers produced by various microorganisms. ^[1]
