2氯4硝基三氟甲氧基苯的氟化反应研究

, 2001
研究了2－氯－4－硝基－α，α，α-三氟甲氧基苯（CNTFMB）的氟化反应，考察了溶剂，相转移催化剂聚乙二醇（PEG6000），KF用量等因素对反应的影响。经实验确定了反应的最佳工艺条件为：n(CNTFMB):n(KF)=1.0:1.4，CNTFMB的质量（g）与溶剂DMF的体积（mL)之比为1：3，n(PEG6000):n(CNTFMB)=0.5:100.0，反应温度135℃，在此条件下，2－氟－4－硝基－α，α，α－三氟甲氧基苯（FNTFMB）的收率为85％，产品纯度w(FNTFMB)=95%

Pd/CNTs金属纳米催化剂的制备及其催化对氯硝基苯加氢性能

, 2017
通过硝酸浸渍法对碳纳米管(CNTs)进行预处理改性,并采用乙二醇液相还原法制备Pd/CNTs纳米催化剂,通过XRD、TEM、BET、拉曼光谱、ICP等手段对其进行表征。结果表明,Pd/CNTs催化剂中Pd的负载量为0.9 wt%,Pd纳米颗粒均匀地分散在CNTs表面,粒径平均大小为5 nm。该催化剂用于对氯硝基苯的选择加氢反应,在常压、60℃下反应2 h,转化率为94.7%,选择性为89.2%

間、對硝苯乙酮光還原反應之理論研究

, 2014
間、對硝苯乙酮在醇中及胺中光還原反應之捉氫原子及捉電子的可能中間體分別以HF/6-31+G**及B3LYP/6-31+G**層次做理論計算，最佳幾何均接近平面構造。硝基捉氫原子之中間體比羰基捉氫原子之中間體的能量低，捉電子之中間體之未成對電子主要分布在硝基上。此可能是對、間硝苯乙酮之光還原選擇性地在硝基反應之原因。 間、對亞硝基苯乙酮在醇中光還原反應之捉氫原子的可能中間體分別以HF/6-31+G**及B3LYP/6-31+G**層次做理論計算，最佳幾何均接近平面構造 ...
