Web1 day ago · Meanwhile, the absorption peak at 881 cm −1 was attributed to the C−C skeleton vibration of the stearic acid (Fig. 7 (d)), and the absorption peak at 776 cm −1 was ascribed to the bending vibration of −(CH 2) n − groups [35]. All the results indicate that the stearic acid has successfully decorated the porous nickel layer surface. Stearic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Stearic acid ( / ˈstɪərɪk / STEER-ik, / stiˈærɪk / stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. The IUPAC name is octadecanoic acid. See more Stearic acid is a saturated fatty acid with an 18-carbon chain. The IUPAC name is octadecanoic acid. It is a waxy solid with the formula CH3(CH2)16CO2H. Its name comes from the Greek word στέαρ "stéar", which means See more Stearic acid is more abundant in animal fat (up to 30%) than in vegetable fat (typically <5%). The important exceptions are the foods See more An isotope labeling study in humans concluded that the fraction of dietary stearic acid that oxidatively desaturates to oleic acid is 2.4 times higher than the fraction of See more In general, the applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. … See more • NIST Chemistry WebBook Entry See more
