Applicability of the quasi-adiabatic enthalpimetric method for the study of chemical kinetics.
The thermal quasi-adiabatic method and the non-adiabatic one are compared for the study of chemical kinetics. With thermistors as temperature-sensitive elements, and a very simple apparatus, moderately fast reactions (with t(1 2 ) down to 2 sec) and consecutive reactions can be followed, and mixtures analysed with good accuracy. The reproducibility is satisfactory over a wide range of experimental conditions. The calculation of the kinetic parameters, for both first-and second-order kinetics is very simple and requires no calibration of the system. Application of the technique to the study of the alkaline hydrolysis of some alkyl acetates is described.
