The chemical structure of the product was characterized by means of the melting point and IR. The results show that tetraethylammonium bromide which was used as a phase transfer catalyst in this reaction had optimization effect on the interfacial diffusive reaction of BTC and PNP. Higher concentration of sodium hydroxide, lower temperature and a higher dosage of BTC produced a small amount of 4-nitrophenyl chloroformate, while lower concentration of sodium hydroxide and a lower dosage of BTC made reaction incomplete, which affected the yield.

结果表明,在碳酸二(4-硝基苯基)酯合成中使用的相转移催化剂四乙基溴化铵对受界面扩散控制的BTC气与对硝基酚钠反应有良好的相转移催化效果;氢氧化钠质量分数较低时,酚钠盐向溶有BTC的油相扩散速度较小,较高时会产生氯甲酸对硝基苯酯;温度较低、BTC量较高时,会产生少量氯甲酸对硝基苯酯,BTC用量较低会使反应不完全,这些都影响着收率。
