摘要: 为探究全氟己酮与2-溴-3,3,3-三氟丙烯(2-BTP)混合药剂对氟化氢生成的抑制效果,本研究搭建了基于杯式燃烧器的试验平台,通过测定氟化氢的生成量,考察不同混合比例对氟化氢产生量的抑制规律。结合量子化学计算与蒙特卡罗模拟,分析全氟己酮的热解路径及各混合比例下氟化氢的生成行为。结果表明,当2-BTP的体积分数为25%~30%时,对氟化氢生成的抑制效果最为显著。由于与羧基相连的C—C键断裂能垒较低,全氟己酮易发生热解;在全氟己酮与2-BTP比例为2∶1时,体系对氟化氢的生成展现出最佳的抑制效果。

Abstract: To investigate the inhibitory effect of the mixture of perfluorohexanone and 2-bromo-3,3,3-trifluoropropene (2-BTP) on hydrogen fluoride generation, a cup-burner-based experimental platform was established in this study. By measuring the amount of hydrogen fluoride generated, the suppression efficiency of different mixing ratios on hydrogen fluoride production was examined. Combined with quantum chemical calculations and Monte Carlo simulations, the pyrolysis pathway of perfluorohexanone and the hydrogen fluoride generation behavior under various mixing ratios were analyzed. The results indicate that when the volume fraction of 2-BTP ranges from 25% to 30%, the inhibitory effect on hydrogen fluoride is the most significant. Due to the low bond dissociation energy of the C—C bond adjacent to the carboxyl group, perfluorohexanone is prone to pyrolysis. The optimal inhibitory effect on hydrogen fluoride generation is achieved when the ratio of perfluorohexanone to 2-BTP is 2∶1.
