Spectroscopic and thermal characterization of chemically modifed 10,12-pentacosadiynoic acid (PCDA) and its sodium salt (PCDA-Na)
Sodium 10,12-pentacosadiynoate (PCDA-Na) was synthesized using two commonly employed neutralization routes involving NaOH and Na₂CO₃. The resulting materials were systematically characterized using FT-IR, PXRD, DSC, TGA, and SEM.
