查询词典 observed

While the adsorptions of l-propanol and 1-Br-propane at 100 癈 give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 癈 shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150 癈, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO2 catalyst.

原位IR光谱实验结果表明：200℃时丙烷／O_2混合气在催化剂表面吸附后的IR谱与同温度下异丙醇吸附的IR谱相似，均检测到吸附态丙酮物种和丙烯醛物种的IR谱峰；溴代异丙烷和异丙醇在催化剂表面吸附后均转化为异丙氧基，异丙氧基主要转化为丙烯和丙酮，丙烯进一步转化为丙烯醛；溴代正丙烷和正丙醇在催化剂表面吸附后均转化为正丙氧基，正丙氧基主要转化为丙醛；丙烯在催化剂表面吸附后转化为σ-氧烯丙基和异丙氧基，升温后σ-氧烯丙基转化为丙烯醛而异丙氧基转化为丙酮。
