摘      要：CHDCOOCHand CHCOOCHwere detected simultane-ously in the trapping reaction with DO as the trapping agent followed bypurging the catalyst with MeOH in Nstream,demonstrating the coexistence ofketene and acetyl intermediates in ethanol synthesis from syngas over *** percentage of deuterated methyl acetate in total AcOMe incrasedwith the ratio of DO/H,indicating that the trapping of ketene strongly com-peted with its further hydrogenation,and implying that ketene was a key C-in-termediate.
