摘要:

采用程序升温法研究Na2SO4·0.5H2O2·H2O在氮气中的热分解动力学,测定Na2SO4·0.5H2O2·H2O分解的TG-DTG和TG-DSC曲线.在8.0 K·min-1、6.1 K·min-1、4.1 K·min-1和2.0 K·min-14个升温速率下,Na2SO4·0.5H2O2·H2O的热分解是简单的一步反应,热分解温度为339.5 K.采用多元非线性回归对Na2SO4·0.5H2O2·H2O在氮气中的热分解动力学模型进行筛选,并利用主曲线法对其分解模型进行判别.Na2SO4·0.5H2O2·H2O的热分解过程受三维相界面控制,分解机理为R3机理.Na2SO4·0.5H2O2·H2O的热分解活化能为70.83 KJ·mol-1,指前因子1.96×103.

Na2SO4·0.5H2O2· Thermal decomposition kinetics of H2O in nitrogen, determination of Na2SO4·0.5H2O2· TG-DTG and TG-DSC curves for H2O decomposition. At 8.0 K·min-1, 6.1 K·min-1, 4.1 K·min-1 and 2.0 K·min-14 heating rates, Na2SO4·0.5H2O2· The thermal decomposition of H2O is a simple one-step reaction with a thermal decomposition temperature of 339.5 K. Multiple nonlinear regression was used to control Na2SO4·0.5H2O2· The thermal decomposition kinetic model of H2O in nitrogen was screened, and the main curve method was used to identify the decomposition model. Na2SO4·0.5H2O2· The thermal decomposition process of H2O is controlled by the three-dimensional phase interface, and the decomposition mechanism is R3 mechanism.Na2SO4·0.5H2O2· The thermal decomposition activation energy of H2O was 70.83 KJ·mol-1, which refers to the pre-factor 1.96×103.
