【摘要】 以1,3,5-三氯苯为原料,在浓硫酸与浓硝酸的作用下硝化成2,4,6-三氯硝基苯。考察了原料配比、反应温度和反应时间,确定了最佳反应条件,在此条件下反应产物的纯度达到99%以上,反应产率达到85%以上。同时,在上述基础上进行硝基三氯苯的破坏性试验,并对可能生成的混硝基三氯苯进行薄层色谱(TCL)分离,再纯化,最后用质谱仪、红外分光光度计、核磁共振波谱仪等进行结构表征。更多还原

【Abstract】 Technology of synthesis of 2,4,8-trichloronitrobenzene by 1,3,5-trichlorobenzene,sulphuric acid and nitric acid was studied.The effect of the reaction temperature,reaction time and raw material mix on the synthesis of 2,4,6-trichloronitrobenzene were studided,which got the suitable processing condition,the concentrations was 99% and the yield of the reaction was 85%.Besides the experiments were done on above-mentioned foundations,using more nitric acid which obtained mix-nitrotrichlorobenzene.Then it was isolated by TLC which employ the different polar.At last it was identified with CC,NS,IR and NMR.更多还原
