Abstract

Global warming is a severe test facing the international community. As a serious greenhouse gas, the emission of SF₆ has been restricted. In recent years, more and more experts and scholars have turned their attention to alternative gases of SF₆. C₅F₁₀O(GWP<1) as an alternative gas is investigated by scientists due to good dielectric properties and weak greenhouse effect in recent years. In the first part, this review introduced the background of SF₆ and C₅F₁₀O. In the second part, we elaborated on four synthetic methods of C₅F₁₀O. Trifluoroacetyl fluoride is the key raw material, CsF is an important catalyst. In the third part, the review presented the dielectric and arc interruption properities of C₅F₁₀O and its mixtures. The addition of O₂ can increased the breakdown voltage of gas mixture. Finally, the decomposition mechanism and products of C₅F₁₀O，C₅F₁₀O/CO₂ or C₅F₁₀O/N₂/O₂ gas mixtures are reviewed.
