Abstract

Oleic acid and its methyl ester were passed through an azeotropic salt bath consisting of 53% KNO3, 40% NaNO2 and 7% NaNO3 at a varying rate at 320° C. Oleic acid was bodied better than its ester. But there is some decarboxylation in the bodied oleic acid. The oleic acid may be polymerized through the interaction of hydroxyl and oxirane as well as of carboxyl and oxirane groups with the formation of ether and ester respectively. The bodied methyl oleate also contains ester, ether and epoxide groups. Vergleichende Untersuchung uber die Polymerisation von Olsaure und Methyloleat in einem azeotropen Salzbad Olsaure und Methyloleat wurden bei 320° C und verschiedenen Durchsatzraten durch ein aus 53% KNO3, 40% NaNo2 und 7% NaNO3 bestehendes azeotropes Salzbad geleitet. Die Olsaure lies sich leichter eindicken als Methyloleat, jedoch findet bei der Olsaure in gewissem Umfang eine Decarboxylierung statt. Die Olsaure wird wahrscheinlich durch Reaktionen zwischen der Hydroxyl- und Oxirangruppe sowie zwischen Carboxyl- und Oxirangruppen polymerisiert, wobei Ather bzw. Ester gebildet werden. Auch das polymerisierte Methyloleat enthalt Ester-, Ather- und Epoxygruppen.
