A hydrofluoroolefin is represented by the following general formula (A): in which, Rf1 and Rf2 are (i) independently linear or branched fluoroalkyl groups having with 1-8 carbon atoms and optionally include one or more catenated heteroatoms; or (ii) bonded together to form a ring structure having 4-8 carbon atoms and optionally include one or more catenated heteroatoms; α is CF3, F, H; β is F or H; γ is CF3, F, CF2H, CFH2, or CH3, and the compound includes a total of 1-4 H atoms; and with the provisos that at least one of α and γ is F or H; when γ is CF3 or F, at least one of α and β is H; when γ is CH3, at least one of α and β is F, and when α is CF3, then β is H and γ is F; wherein at least one of Rf1 and Rf2 have two or more carbon atoms.
氢氟烯烃由以下通式 (A) 表示:其中,Rf1 和 Rf2 是:(i) 独立的线性或支链氟烷基,具有 1-8 个碳原子,可选择包括一个或多个烯化杂原子;或 (ii) 键合在一起形成环状结构,具有 4-8 个碳原子,可选择包括一个或多个烯化杂原子;α 是 CF3、F、H;β 是 F 或 H;γ是CF3、F、CF2H、CFH2或CH3,且该化合物总共包括1-4个H原子;但前提是α和γ中至少有一个是F或H;当γ是CF3或F时,α和β中至少有一个是H;当 γ 是 CH3 时,α 和 β 中至少有一个是 F,当 α 是 CF3 时,则 β 是 H,γ 是 F;其中 Rf1 和 Rf2 中至少有一个具有两个或两个以上的碳原子。
