Physikalische Eigenschaften homologer kristallisierter Reihen mit alternierendem und nicht alternierendem Schmelzpunkt

Abstract: Es wurde untersucht, ob in homologen Reihen mit alternierenden Schmelzpunkten auch ande,re Eigenschaften alternieren. Als Reihen rnit alternierendem Schmelzpunkt wurden n-Dicarbonsauren und Phenyl-alkyl-methanole untersucht. Sie zeigen stark alternierende Loslichkeiten. Dagegen sind die Dichten in fe.stem Zustand bei 210 C, die Dielektrizitatskonstanten bei ZOO C (fest) und bei 60° C (fliissig) innerhalb unserer Mengenauigkeit nicht alternierend. -Eine homologe Kontrollreihe mit nicht alternierenden Schmelzpun… Show more

“…Thus, 9-carboxystearic acid is a derivative of sebacic acid (2-nonyldecanedioic acid), an even-numbered acid, and 10-carboxystearic acid is a derivative of undecanedioic acid (2-octylundecanedioic acid), an odd-numbered acid. The alternating effects shown by the unsubstituted, a,co-alkanedioic acids in both melting point (15) and solubility properties (16) are well known and have been shown to result from differences in crystal structure (17)(18)(19)(20). Evennumbered dibasic acids have higher melting points than the odd-numbered ones (Table III).…”
