Zusammenfassung

Die Anwendung der automatischen Dampfraumanalyse zur Dampfdruckbestimmung wird beschrieben. Die bei verschiedenen Temperaturen ermittelten Dampfdrucke von 1-Chlornaphthalin, Anthracen, γ-Hexachlorocyclohexan und Hexachlorbenzol befinden sich in guter Übereinstimmung mit den Literaturangaben. Die untere Grenze der Anwendbarkeit liegt bei 0,01 Pa.

Summary

The application of automated headspace gaschromatography for the determination of vapour pressures is described. The vapour pressures determined at different temperatures for 1-chloronaphthalene, anthracene, γ-hexachlorocyclohexane and hexachlorobenzene agree well with the data from literature. The lower limit of applicability of the method is in the range of 0.01 Pa.
