Abstract

Estimates are made showing that when an exothermal reaction proceeds in an isothermal medium (in a thermostat), self-heating occurs, whose values are determined by the competition between the processes of heat input and heat removal. Relationships are obtained that make it possible to estimate the deviation of the observed values of the kinetic parameters from the true values and to reveal the influence of various parameters on these deviations.

等温条件下自加热对放热反应动力学的影响

摘要估计结果表明，当放热反应在等温介质（恒温器）中进行时，会产生自热，其值由热量输入和热量排出过程之间的竞争决定。通过这些关系，可以估算出观察到的动力学参数值与真实值的偏差，并揭示出各种参数对这些偏差的影响。
