| 概要 |
Phase diagrams for the binary systems of symmetric long chain ketone and n-alkane (Kn/Cn, n: the number of carbon atoms) were determined by DSC and polarizing microscopic observations. The systems of ...K25/Cn, ranging from C25 to C29, was examined. These systems had similar characteristics in the phase diagram. It consisted of two regions of solid solution for lower concentrations of K25 and eutectic for higher ones. The critical concentration between these two regions increased as the difference in the chain length of both components was increased. This behavior was interpreted in terms of entropy contribution from transversal and longitudinal dispositions of ketone molecules. The systems of K29/C29 and K39/C39 were also examined. The critical concentration increased with the increase of chain length.続きを見る
