Ammonium palmitate is a chemical compound with the chemical formula CH3(CH2)14COONH4.[1] This is an organic ammonium salt of palmitic acid.[2]
Synthesis
Ammonium palmitate can be prepared by reacting palmitic acid and excess 28-30% NH3-solution.
Physical properties
Ammonium palmitate forms yellow-white powder, soluble in water.[3] It is slightly soluble in benzene and xylene, practically insoluble in acetone, ethanol, methanol, CCl4, or naphtha.[4][5]
X-ray diffraction studies of ammonium palmitate show crystals that belong to monoclinic space group P21/n.[6]
Uses
The compound is used to produce waterproofing fabrics[7] and for thickening lubricants.
