    Thermokinetic Research Method for Simple-order Reactions. Double-thermoanalytical curve method (2000)
    Springer
    Journal of thermal analysis and calorimetry 61 (2000), S. 219-228 
    Details
    ISSN: 1572-8943
    Keywords: calorimetry ; double-thermoanalytical curve method ; simple-order reactions ; thermokinetics

    Topics: Chemistry and Pharmacology
    Notes: Abstract A novel thermokinetic research method for determination of the rate constant of a reaction taking place in a batch conduction calorimeter under isothermal conditions is proposed: the double-thermoanalytical curve method. The method needs only the characteristic time parameter t m, the peak height Δm at time t m and the peak area a*m after time t m for two thermoanalytical curves measured with different initial concentrations of the reactants: it conveniently calculates the rate constants. The thermokinetics of four reaction systems were studied with this method, and its validity was verified by the experimental results.

    Thermokinetic Research Method for Faster First-order Reaction. Double-parameter method (2000)
    Springer
    Journal of thermal analysis and calorimetry 63 (2000), S. 415-421 
    Details
    ISSN: 1572-8943
    Keywords: double-parameter method ; faster first-order reaction ; thermokinetic research method ; thermokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract This paper presents a novel data processing method for thermokinetics of faster first-order reaction on the basis of the double-parameter theoretical model of a conduction calorimeter, in which the rate constant of a first-order reaction can be calculated from only four peak height data from the same thermoanalytical curve without using any peak-area. The saponifications of ethyl acetate and methyl acetate in aqueous solution and ethyl benzoate in aqueous alcohol have been studied to test the validity of this method. The rate constants calculated with this method are in fair agreement with those in literature; hence the validity of this method is demonstrated.

    Time-variable Method for Studying Reaction Rates in a Calorimeter (1999)
    Springer
    Journal of thermal analysis and calorimetry 58 (1999), S. 477-485 
    Details
    ISSN: 1572-8943
    Keywords: calorimetry ; thermokinetics ; time variable method
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A novel method for the determination of rate constants of reactions, the time-variable method, is proposed in this paper. The method needs only three time points (t), peak heights (Δ) and pre-peak areas (α), obtained from the measured thermoanalytical curve. It does not require the thermokinetic reaction to be completed. It utilizes data-processing on a computer to give the rate constants. Four reaction systems, including a first-order reaction, second-order reactions (with equal concentrations and with unequal concentrations) and a third-order reaction, were studied with this method. The method was validated and its theoretical basis was verified by the experimental results.
