In this dissertation, the liquid phase oxidant of p-nitrotoluene and 2,4-dimethylnitrobenzene with oxygen/air to aromatic acid was discussed.

论文研究了氧气液相氧化对硝基甲苯、2，4-二甲基硝基苯制取对硝基苯甲酸、3-甲基-4-硝基苯甲酸的反应。

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。

We have synthesized 4,4'-dinitro-3 4''-dimethyl triphenylamine,(1), in 84% yield in an one-step condensation process between 3,4-dimethyl aniline and 4-fluoro-nitrobenzene. After the auto-oxidation of (1) and the subsequent hydrogenation of the nitro-groups, an AB2 type triphenylamine polyimide intermediate bearing two amine groups and one acid-anhydride group each on individual phenyl ring,{AB2 PI Intermediate}, was prepared successfully. The yields of the autoxidation and the hydrogenation steps are 81% and 90% respectively.

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
