Sulfur hexafluoride (SF6), which is known as a superior electrically insulating and arc-quenching medium, plays a decisive role in the modern transmission and distribution network of electric energy, especially in high-voltage power networks. However, the ever-increasing usage of SF6 also leads to the continuous escalation of atmospheric SF6 levels, which is considered to be the main cause of the greenhouse effect. To decrease this environmental impact, eco-friendly alternatives to SF6 have been researched for decades. To date, no significant success has been made regarding replacement gases for transmission networks. Some potential alternatives have comparatively lower global warming potential (GWP) but involve technical trade-offs. Thiazyl trifluoride, which has some excellent chemical and electric properties, is a novel substitution candidate for SF6. In this article, an efficient synthetic route starting from sulfur monochloride and followed by ammonization and fluorination was proposed. The structures of the intermediates and the target products were determined by X-ray diffraction (XRD), infrared spectroscopy (IR), and gas chromatography-mass spectrometry (GC-MS). The effects of some determining factors on the yield and purity, including the molar ratio of the reactants, recrystallization conditions and condensation temperature, were also investigated. The results showed that the overall yield of thiazyl trifluoride was approximately 25%, while the purity could be up to 90.6% under optimal conditions.

环保绝缘气体噻唑三氟的合成及介电性能
六氟化硫（SF 6）被称为优良的电绝缘和灭弧介质，在现代电能输配电网络中，特别是在高压电网中起着举足轻重的作用。然而，SF 6使用量的不断增加也导致大气中SF 6水平的不断升高，这被认为是温室效应的主要原因。为了减少这种环境影响，SF 6的环保替代品已经研究了几十年。迄今为止，在传输网络的替代气体方面尚未取得重大成功。一些潜在的替代品具有相对较低的全球变暖潜能值 (GWP)，但涉及技术权衡。三氟噻唑具有一些优异的化学和电学性能，是SF 6的新型替代候选物. 本文提出了以一氯化硫为原料，经氨化、氟化的高效合成路线。通过 X 射线衍射 (XRD)、红外光谱 (IR) 和气相色谱-质谱 (GC-MS) 确定了中间体和目标产物的结构。还研究了反应物的摩尔比、重结晶条件和冷凝温度等一些决定因素对收率和纯度的影响。结果表明，噻唑三氟的总收率约为25%，在最佳条件下纯度可达90.6%。
