    Notes: Abstract A scheme for the development of equations for the transport properties in terms of pressure and temperature, so-called transport equations of state, is presented. The surfaces of transport properties and density as a function of pressure and temperature reveal similarities, which become even more evident when the residual transport property as a function of pressure and temperature is considered. Even the spinodals of transport and thermal properties coincide in the p, T plane, as can be shown mathematically and as was already empirically found for water and oxygen. Based on these similarities a cubic transport equation of state is evaluated for the residual thermal conductivity of oxygen. The new equation is only a little less accurate than the already established virial transport equation of state for oxygen. It is, however, much simpler and needs only a few parameters. The accuracy is still good enough for practical applications. The results demonstrate that cubic equations of state can describe transport properties and are a basis for generalized estimation methods for the transport properties of fluids.

    Notes: Abstract The development of the MIDAS Data-Bank System from its origin as part of the first DECHEMA properties data project in 1977 is described. The system concentrates the rapidly increasing amount of data for the viscosity and thermal conductivity for pure fluids and fluid mixtures by evaluation of the most reliable data sets. The data sets are represented by density-temperature correlations which are the customary method to correlate transport properties. To allow for a direct calculation of the transport properties from given pressures and temperatures, a new type of equation has been developed. As an example, the simultaneous representation of the viscosity and thermal conductivity of oxygen by one transport equation of state is discussed.

    Notes: Das untersuchte Ö1 von Eucalyptus dives enthielt 35% Piperiton, das sich mit Ferrichlorid in einer Ausbeute von 90% zu Thymol oxydieren ließ. Bei neutraler Permanganat-oxydation wurde Diosphenol erhalten. Ferner wurde in dem Öl Terpinenol-4 und eine Oxysäure C18H34O3 aufgefunden.

    Notes: Die Einwirkung der Ferrocyanwasserstoffsäure auf bicyclische Terpene führte zu interessanten Ergebnissen, die im folgenden kurz zusammengefaßt sind: I1Die bicyclische Terpene, Camphen, α-Pinen und No-pinen vereinigen sich mit der Ferrocyanwasserstoffsäure unter Bildung fester, sehr beständiger Verbindungen nach folgender Gleichung:\documentclass{article}\pagestyle{empty}\begin{document}$$ 2{\rm C}_{10} {\rm H}_{{\rm 16}} + {\rm H}_{\rm 4} {\rm FeCy}_{\rm 6} = ({\rm C}_{{\rm 10}} {\rm H}_{{\rm 17}})_2 {\rm H}_{\rm 2} {\rm FeCy}_{\rm 6} $$\end{document}2Diese Verbindungen lassen sich nur spalten, wenn sie mit überschüssiger Lauge mehrere Stunden bei etwa 160° (im Autoklaven) erhitzt werden. Es entstehen dabei (neben Terpenen) Alkohole und Basen:a)aus Camphen: Camphenhydrat und Isoborneol (neben Camphen) sowie Isobornylamin;b)aus α-Pinen : α-Terpineol (neben Limonen) sowie Isobornylamin, verunreinigt mit Isofenchylamin;c)aus Nopinen: α- Terpineol (neben Limonen), sowie Isofenchylamin.3Es wird angenommen, daß die Alkohole und Basen von verschiedenen isomeren Verbindungen der Ferrocyanwasserstoffsäure sich ableiten: die Alkohole entstehen durch Verseifung wahrer Ester der Ferrocyanwasserstoffsäure, die Basenbilden sich aus Verbindungen, in denen der Isobornyl- bzw. Isofenchylrest an den Stickstoff der Cyangruppen gebunden ist. Eine Trennung der Anlagerungsverbindungen ist bisher noch nicht gelungen.Der aus Camphen entstehende Isobornylester zeigt übrigem die für alle Ester des Isoborneols charakteristischen Isomerisationserscheinungen.IIVon der Ferrocyanwasserstoffsäure werden ferner die Autoxydationsprodukte des Pinens und das bei der Hydratation zu Terpinhydrat intermediär entstehende Terpineol als leicht spaltbare Oxoniumsalze gebunden.
