✦ Synopsis

A method is described which estimates (using least-squares analysis) all parameters (kinetic parameters and also zero and infinite time assays) from nonisothermal kinetic data. This method overcomes the time delays required for infinite time assays and biased estimates caused by the use of those assay results. Flexible temperature and data collection programs can he used. The mathematical models account for thermal volume expansion and the appropriate model is selected by statistical tests (provided the reaction is studied over -90% decomposition). The models use a reparameterized Arrhenius equation in which the frequency factor is replaced by k,, the rate constant a t a specified temperature. This improves the numerical procedure and allows room temperature stability to be estimated directly.
