由合成气直接合成低碳混合醇,是C_1化学领域中的重要研究课题.对于低碳醇合成的反应机理,国内外有关学者在归纳宏观和部分微观实验结果的基础上曾提出几种观点.近几年以来,国内有关学者从反应微观动态检测着手,较系统地研究了CO+H~2反应合成醇的反应机理.本室曾利用“原位”透射红外·脉冲应答法,“原位”红外·化学捕获法,“原位”发射红外脉冲应答法对低碳醇合成反应过程中催化剂表面上反应物的吸附态、中间物的形成及其 The direct synthesis of low-carbon mixed alcohols from syngas is an important research topic in the field of C 1 chemistry.For the reaction mechanism of the synthesis of lower alcohols, relevant scholars at home and abroad have put forward several views based on the macro and some microscopic experimental results. In recent years, relevant scholars from the reaction microscopic dynamic detection proceed with a systematic study of the reaction mechanism of CO + H ~ 2 reaction of alcohol synthesis .This chamber has been the use of “in situ” transmission infrared pulse response method, “in situ ”Infrared chemical trapping method, the“ in-situ ”emission infrared pulse response method for the adsorption of reactants on the catalyst surface during the synthesis of lower alcohols, the formation of intermediates and their
