| 摘 要： | 本文报道树脂法从混合物中分离纯化邻硝基苯甲醛的方法。研究说明，通过伯胺树脂与醛的反应对邻硝基苯甲醛进行化学吸附，可以将邻硝基苯甲醛从含有邻硝基甲苯、邻硝基苯甲醛、邻硝基溴苄、邻硝基－α，α─二溴苄、以及邻硝基苄醇的混合物中有效地分离出来。 |
| 关 键 词： | 伯胺树脂，邻硝基苯甲醛的分离 |

| Abstract: | A method for separation of o - nitrob(3nzaldehyde was described. When a mixture containing o - nitrobenzaldehyde(55 % ), o - nitrotoluene(35 % ), o - nitrobenzylbromide(3 % ) 3 o-nitrobenzyl alcohol(2% ), and o- nitrobenzylidene dibromide (5%) was passed through a column packed with a amino resin, o - nitrobenzaldehyde was adsorbed chemically on the resin. o -Nitrobenzaldehyde on the resin could be eluated from the column by 2 mol/l HCl in ethanol. |
| Keywords: | Amino resin Separation of o-nitrobenzaldehyde |
