二(对-硝基苯基)磷酸酯合成工艺的改进

摘要

对硝基苯酚和三氯氧磷以乙酸乙酯作溶剂在吡啶的作用下进行反应，最后水解得二(对-硝基苯基)磷酸酯。改进后的工艺革除了苯和乙腈，降低了毒性和成本。%p-Nitrophenol was treated with phosphorous oxychloride and pyridine in ethyl acetate,then hydrolyzation gave the di-p-nitrophenyl hydrogen phosphate.This technique cut off benzene and acetonitrile,weakened the toxicity,reduced the production cost.
