摘要:
该文采用定量拉曼光谱法测定混酸体系中NO+ 2 的质量摩尔浓度 ,做出浓度三角图 ;讨论间歇硝化的不同加料方式对反应体系中NO+ 2 的质量摩尔浓度的影响。传统的包含配酸操作的正加法和反加法均不利于硝化反应的平稳进行。该文建议将硝酸和硫酸分开加入 :一种作为溶剂 ;另一种则滴加进入体系。对于活性较高的芳烃 ,应用硫酸作溶剂 ;而对于活性较低的芳烃 ,应用硝酸作溶剂
Abstract:
Quant itative Raman spectra was employed to invest igate the concentrat ion of n-i t ronium ion in mix ing acid system and a triangular diagram w as made to denote the results, w hich w as used to study the materia-l int roduct ion mode in intermit tent nit rat ion operations. T he inf luence of various mode on nitronium concentration in the nit rat ion systems w as discussed. It w as found that dropping mix ing acid into aromatic substrate makes nit ronium concent rat ion change too much and dropping aromatic subst rate into mix ing acid may bring too much by-products. It w as suggested that nit ric and sulfuric acid should be int roduced separately. For reactive arenes, sulfuric acid should be used as solvent and nit ric acid is the dropping agent ; for unreactive arenes, nit ric acid should be used as solvent and sulfuric acid is the dropping agent.
