Abstract

N(C5F11)3 (Fluorint FC-70) has been chosen as the test material to compare the chemicophysical data obtained by static-sample and DSC methods.

The normal boiling point, the molar enthalpy of vaporization, and the constants of the Antoine equation of fluorint FC-70 are reported.

DSC can be developed into a simple and rapid routine instrument to determine the enthalpy of vaporization as well as the boiling point of liquid, particularly at relative high temperature.

Zusammenfassung

Zum Vergleich der mittels konventioneller und DSC-Methoden erhaltenen chemischphysikalischen Daten wurde die Testsubstanz N(C5F11)3 (Fluorint FC-70) gewählt.

Der normale Siedepunkt, die molare Verdampfungsenthalpie und die Konstanten der Antoine-Gleichung von Fluorint FC-70 wurden beschrieben.

DSC kann zu einem einfachen und schnellen Routinegerät zur Bestimmung der Verdampfungsenthalpie und auch des Siedepunktes von Flüssigkeiten, speziell bei hohen Temperaturen entwickelt werden.
