| Popis: | 102 (3,4-Epoxycyclohexane) methyl-3’4’-epoxycyclohexyl-carboxylate (EEC) is a typical epoxy resin (EP). In Asia, due to the unstable reactive natures of epoxy resin (EP), various thermal hazard and runaway reaction incidents have been occasioned by EP in the manufacturing process, such as fire, explosion, and toxic release, resulting in loss of life as well financial catastrophes and social outcries. Certain catalysis substances, sulfuric acid (H2SO4), acetic acid (AA), or sodium hydroxide (NaOH), may accelerate the reaction or curing rate for EP. However, an incompatible reaction with these chemical substances may induce a thermal hazard, causing a runaway excursion during the last stage. We employed thermal analysis and product’s analysis technology to obtain thermal stability parameters and reaction mechanism to evaluate the incompatible hazard of EEC mixed with its reactants. The experimental data were compared with kinetics-based curve fitting to assess thermally hazardous phenomena by optimizing curve fitting on the kinetic parameters. The aim of this study was to estimate the incompatible hazards for EEC, provide thermal hazard information in order to determine the optimum operation conditions, and diminish the likelihood of fire and explosion accidents incurred by EP. |
