炔丙醇在多孔Pt黑电极上,0.5mol·dm~(-3)HClO_4溶液中电还原的MSCV研究结果表明炔丙醇电还原时既涉及烯丙基上C—OH断键反应亦涉及炔丙基上C—OH断键反应生成烃类.此外有少量炔丙醇直接质子化生成部分饱和的烯丙醇.表征各种反应产物的m/z的质谱电流-电极电位扫描曲线(I_(M-φ))详细描绘了各分步反应的图象.各m/z的lgI_(M-φ)曲线在一定电位范围内呈线性,并求得它们的Tafel斜率.依据实验结果对反应机理进行了详细分析.
Propargyl alcohol at porous Pt black electrode, 0.5mol · dm ~ (-3) HClO_4 solution electrocatalytic reduction of MSCV research results show that propargyl alcohol reduction involves both allyl C-OH bond breaking reaction is also involved in alkyne The C-OH bond on the propyl group reacts to form hydrocarbons. In addition, a small amount of propargyl alcohol is directly protonated to form partially saturated allyl alcohol. The mass spectrum current-electrode potential scan curve characterizing the m / z of various reaction products (I_ M-φ)), the lgI_ (M-φ) curves of each m / z are linear over a range of potentials and their Tafel slopes are obtained.According to the experimental results, the reaction mechanism Conducted a detailed analysis.
