Abstract
Phase equilibria in a three-component system composed of dibasic acids (hexanedioic, pentanedioic and nonanedioic) are investigated by means of differential thermal analysis. The eutectic composition is determined: 48.0 wt % pentanedioic acid, 20.0 wt % hexanedioic acid, and 32.0% nonanedioic acid. The melting temperature of the alloy is 70°C. It is concluded that this eutectic composition can be used to prepare electrolyte for thin-layer anodization.
