答案

H2O +LiPF6 → POF3 +LiF + 2HF
LiPF6→ LiF + PF5
H2O+ PF5 → POF3+ 2HF
H2O + POF3→ PO2F + 2HF
2H2O + PO2F → H3PO4+ HF
H2O + (CH2O CO2 Li) 2→ Li2CO3 + CO↑
RO CO2 Li + HF→ ROCO2H + LiF
Li2 CO3+2HF → H2CO3+ 2LiF
LiPF5 → LiF＋ PF5
PF5＋ H2O → 2HF ＋ POF3
C4H8O3(EMC)＋ PF5 → C2H5OCOOPF4 + HF+ C2H6↑
Li2CO3＋ 2HF → 2LiF + H2O ＋ CO2↑
DEC + e + 2Li+ →C2H5OCO2Li (s) + CH3 •
DEC + e + 2Li+ →C2H5OLi (s) + C2H5CO2•
C2H5CO2• + CH3•→CH3OCO2CH3
CH3 •+ 1/2H2 • →CH4↑
CH3•+ CH3•→ C2H6 ↑
DEC + 2e + 2Li+→C2H5OLi (s)+CO↑
