Sulfuryl fluoride (SO2F2) plays an important role in the operation of gas-insulated switchgear (GIS) equipment where it is widely used as the characteristic gas for discharge diagnostics. However, the formation mechanism of SO2F2 is currently unclear, and as a consequence, we have employed a range of ab initio methods to investigate the hydrolysis reaction of SOF4 that is known to afford SO2F2 in the gas phase. These results suggest that two H2O molecules are incorporated into a low energy transition state to afford an H-bond network that facilitates proton transfer during the hydrolysis of SOF4.

催化水分子在亚硫酰四氟化物(SOF4)水解中作用的理论研究。
硫酰氟(SO 2 F 2)在气体绝缘开关设备(GIS)设备的运行中起着重要作用,在该设备中,该设备被广泛用作放电诊断的特征气体。然而,目前尚不清楚SO 2 F 2的形成机理,因此,我们采用了从头算的方法研究SOF 4的水解反应,已知该SOF 4在气相中可提供SO 2 F 2。这些结果表明,两个H 2 O分子被掺入低能跃迁状态,以提供在SOF水解过程中促进质子转移的H键网络。4。
