SPECTROSCOPIC AND THERMOGRAVIMETRIC EXAMINATION OF NEODYMIUM PALMITATE AND NEODYMIUM STEARATE

, 2022
IR, X-ray diffraction and thermogravimetric studies were used to illustrate the structure of neodymium palmitate and stearate in solid state. IR results reveals that the fatty acids exists with dimeric structure through intermolecular hydrogen bonding and neodymium Palmitate and Stearate were ionic in nature.
