摘要:
对甲基磺酸和金属锡粒合成甲基磺酸亚锡新工艺的反应表观动力学进行了研究.考察了不同温度下甲基磺酸浓度随时间的变化率,结合阿累尼乌斯公式采用最小二乘法处理实验数据,得到了不同温度下的该反应的表现反应动力学速度常数和表观活化能.结果表明,甲基磺酸与金属锡生成甲基磺酸亚锡的化学反应是液-固相表面反应,属于零级反应.在393.15～423.15 K范围内,该反应的表观活化能为27.02 kJ·mol-1.
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.
