mm. In a typical experiment, known amounts of Ru and/or Co
catalysts, LiI or another promoter, and 2 mL DMI or another
solvent were loaded sequentially into the reactor. The reactor
was filled with DME of saturated vapor pressure (0.5 MPa) at
room temperature after the reactor was purged three times

bath of constant temperature, and the magnetic stirrer was
started at 800 rpm. After reaction, the reactor was cooled in
an ice-water bath for 1 h, the residual gas was released slowly
and collected in a gasbag. The liquid mixture was analyzed by
GC (Agilent 7890B) equipped with a flame ionization detector
and an HP-5 capillary column (0.32 mm in diameter, 30 m in
length) using toluene as the internal standard. Identification of
the liquid products was done using a GC-MS (Agilent-7890B-
