Theoretical Analysis of the Thermal Decomposition Kinetics of Sodium Percarbonate and Its Experimental Verification

WANG Hong-xian1,ZHAO Hong-kun2(1.School of Chemistry and Chemical Engineering,Nantong University,Nantong 226007,China;2.School of Chemistry and Chemical Engineering,Yangzhou University,Yangzhou 225000,China)  
In this paper,the preparation of sodium percarbonate in modified wet method was referred and the experiment for decomposition of sodium percarbonate in nitrogen gas and air was provided.The thermal decomposition kinetics experiment of sodium percarbonate was statistically designed in theory and the optimum experimental position was determined.The results were confirmed by the experiment that the optimum experimental positions were 10 percent and 85 percent of reaction fraction.When the experiment was done at the two points,the relative error of k was least.
