Abstract

A modified sealed tube method has been developed allowing more accurate measurements, greater reproducibility, and more precise data collection. The method is applied to normal alkanes from n-octane to n-hexadecane and two normal alcohols. Since alkanes decompose starting with n-decane, a kinetic analysis based on an irreversible first order unimolecular reaction is used to linearize the apparent critical temperature versus time curve and perform a more certain extrapolation. The method is successful since the temperature history of the substance is recorded by a computer, and ampoule contents are analyzed at the experiment completion. The approach is general since many hydrocarbon decompositions can be described empirically by a first order rate expression. New critical constants are reported and compared to previous experimental values and correlations.
