Study on Synthesis and Thermal Decomposition Kinetics of Mg(OH)2 Modified with SDBS by Liquid Phase Method

The Thermal Decomposition Kinetics of Mg(OH)2 Modified with Sodium Dodecyl Benzene Sulfonate (SDBS) by the Liquid Phase Method Was Investigated Using Differential Thermal Analysis and Thermo Gravimetric (DTA-TG) at Different Heating Rates. the Results Show that the Mg(OH)2 Modified with SDBS Is Mg(OH)2 with Hexagonal Phase Structure. the Average Apparent Activation Energy of the Decomposition Stages of Mg(OH)2 Modified with SDBS Was Calculated Using the Doyle-Ozawa and Kissinger Methods as 169.13 Kj•mol-1. the Reaction Order and Frequency Factor Can Be Also Determined by Kissinger Method. the Kinetics Equations of Reaction Were Deduced as Dα/dt = (5.71×1012/β) e-20340/T (1-α)1.52.
