摘要
为研究过氧化氢异丙苯(CHP)的热稳定性,本文利用C600微型量热仪对CHP和CHP与NaOH的混合物在空气中受热分解的反应和放热特性进行了实验研究。同时通过GC/MS分析了CHP和不同浓度NaOH混合后的产物组成,并利用气相色谱仪对各产物进行了定量分析,结果得出高浓度氢氧化钠催化CHP分解产物主要是2-苯基-2-丙醇,低浓度时的主要产物是乙酰苯。氢氧化钠催化CHP分解产物的组成与其浓度相关。
In order to study the influence of sodium hydroxide on the thermal hazard of cumene hydroperoxide （CHP）, the thermal decomposition of CHP and CHP mixtures with different content of sodium hydroxide in the air was studied by C600 Calorimeter. CHP reacted with various concentrations of dilute sodium hydroxide as a catalyst to cleave at ambient and decomposition temperature. The products were verified by GC/MS, and were quantitatively analyzed by chromatography. CHP cleaved heterolytic with high concentrations of dilute sodium at 30 - 260 ~C, whose major product was dimethylphenyl （DMPC）. However, the main products became acetophenone by cleaved hemolytic pathway. The catalytic concentrations of NaOH significantly affected the composition products of reactions of cumene hydroperoxide mixed with sodium hydroxide.
