摘　　要：利用原位红外技术研究了CO+H2在Fe-Co-Cu催化剂上合成低碳醇的碳链增长机理。红外光谱证实了'中间物'——酰基和羟基次甲基的存在;并确认它们是CO+H2合成C2醇的'中间物',从而得出结论:在Fe-Co-Cu催化剂上,CO+H2合成醇的碳链增长机理按缩合理论进行。The mechanism of carbon chain growth in the synthesis of lower carbon alcohols from CO+H_2 over Fe-Co-Cu catalyst was studied by the use of in-situ IR technique. The IR spectra have demonstrated the existence of 'intermediates' acy group and hydroxyl-methylidyne and confirmed that they were the 'intermediates' in the synthesis of C_2 alcohols from CO + H_2. Therefore, it was concluded that the mechanism of carbon chain growth in the synthesis of alchols from CO+H_2 over Fe-Co-Cu was based on the condensation theory.
