General description
Stearic acid (SA) is a straight chain fatty acid. It forms ordered monolayered Langmuir-Blodgett (LB) films on the surface of germanium. These LB films have been investigated by Fourier transform-infrared (FTIR)-attenuated total reflection (AR) spectra.
Conversion of SA with >98% selectivity to deoxygenated C17 products by employing carbon supported palladium catalyst has been reported. It is a promising phase change material (PCM) due to its non-toxicity and convenient melting temperature. Also, it exhibits almost negligible supercooling while undergoing phase change.

Application
Stearic acid can undergo esterification in the presence of mesoporous solid acid catalysts to form methyl stearate. Due to its waterproof ability, STA may be used to impart superhydrophobicity on various surfaces. STA may also be used in the preparation of stearic acid self-assembled monolayers.
Stearic acid may be used to compose the core during sol-gel synthesis of nanoencapsulated phase change materials (NEPCMs).
