【摘要】 为了提高环氧丙烯酸酯合成的安全性，采用量热法研究了丙烯酸与双酚A型环氧树脂的开环酯化反应，重点探索副反应的条件和评估绝热条件下的热危害。使用反应量热仪（RC1mx）研究了催化剂三乙胺（TEA）用量1.0%、0.6%和0.3%时对环氧丙烯酸酯工业合成过程热行为的影响。差示扫描量热法（DSC）和绝热量热法（ARC）用于研究初始放热温度（T₀）、峰值放热温度（T_p）、反应热（ΔH）和反应的失控特性。结果表明，在工艺温度为60℃～110℃时，反应风险因子为6～10，热危险程度为中等。最后，根据相关数据和风险等级，提出了降低过程风险的建议和措施。本研究为环氧丙烯酸酯合成反应的安全管控、配方优化以及工业安全生产提供了重要的理论依据和实践指导，具备显著的工程应用价值。更多还原

【Abstract】 To improve the safety of epoxy acrylate synthesis, this study used calorimetry to investigate the ring opening esterification reaction between acrylic acid and bisphenol A-type epoxy resin, focusing on exploring the conditions of side reactions and evaluating the thermal hazards under adiabatic conditions. The effect of catalyst concentration on the thermal behavior of epoxy acrylate industrial synthesis process was studied using a reaction calorimeter（RC1mx）. The effect of catalyst concentration on the thermal behavior of epoxy acrylate industrial synthesis process was studied using RC1mx. Differential scanning calorimetry（DSC） and adiabatic calorimetry（ARC） are used to study the initial heat release temperature（T₀）, peak heat release temperature（T_p）, reaction heat（ΔH）and runaway characteristics of the reaction. The results show that when the process temperature is between 60℃ and 110℃, the reaction risk factor is 6 to 10, and the degree of thermal hazard is moderate. Based on relevant data and risk levels, suggestions and measures to reduce process risks have been proposed. This study provides important theoretical basis and practical guidance for the safety control, formulation optimization, and industrial safety production of epoxy acrylate synthesis reactions, and has significant engineering application value.更多还原
