| Abstract: | 1-Bromo-2-(p-nitrophenoxy)ethane was synthesized in the reaction of p-nitrophenol with ethylene dibromide as an organic intermediate, in which 1,2-di-(p-nitrophenoxy)ethane formed as a byproduct; To separate two compounds, their solubility properties were studied in this article. By using selective solvent such as petroleum ether, they could be separated and thus the objective product with good quality was obtained. |
