- Abstract:
-
The apparent kinetics of the reaction of the new process of synthesizing stannous methanesulfonate with methanesulfonic acid and metal tin grains were studied. The change rate of methanesulfonic acid concentration with time was investigated, and the experimental data were processed by least squares method combined with Arrhenius’ formula, and the reaction kinetic velocity constant and apparent activation energy of the reaction were obtained at different temperatures. The results show that the chemical reaction between methanesulfonic acid and metallic tin to form stannous methanesulfonate is a liquid-solid surface reaction, which belongs to the zero-order reaction. In the range of 393.15~423.15 K, the apparent activation energy of the reaction was 27.02 kJ·mol-1.
