摘要
采用等温法对文献中提及的两种分解动力学模型—核形成、核增长模型和自催化模型进行了判别。对于一条α-t曲线,t_1/t_2=Const时,t_1和t_2对应的分解率α_1和α_2是不同的,以α_1对α_2作图,并与理论曲线进行比较。结果表明,过碳酸钠的分解动力学模型为自催化模型。
Two models of decomposition kinetics-nucleation growth and autocatalytic are distinguished by using isothermal method. For a certain a - t curve, at is different from a2 when t, /% equals to constant . Plotting a( to az , and comparing with theoretical curve, then the decomposition kinetics model of sodium percarbonate can be obtained . The results indicate that it is autocatalytic.
