The results showed that the fiber had the function of absorbing toluene and trichloroethylene after introducing HEMA into macromolecules, and the absorptive process obeyed Hill equation of sigmoidal model.Toluene and trichloroethylene absorbency increased with the increase of mass fraction of HEMA,and their maximum absorbency was 10 g/g and 21 g/g,respectively.The ratio of remaining fiber also increased with the increase of mass fraction of HEMA to make organic liquid retention ratio strengthen.Furthermore,dynamic mechanical performance of the fiber was affected by mass fraction of HEMA obviously, and the segments movement was influenced more obviously.At the same time,mass fraction of HEMA had a great impact on the surface and cross section morphologies,especially,many cavities existed in surface, and cross section had a lot of holes with asymmetric size when mass fraction of HEMA was equal to 15 wt%.

结果表明，HEMA引入大分子后，所得纤维对有机液体甲苯、三氯乙烯具有吸附功能，且吸附过程符合sigmoidal模型中的Hill方程；随HEMA质量分数的增加，纤维对甲苯和三氯乙烯的饱和吸附量增大，对甲苯和三氯乙烯的最大吸附量分别可达10 g/g和21 g/g；随HEMA质量分数的增加，纤维剩余率增加的同时，使纤维对甲苯和三氯乙烯的握持能力增强；HEMA质量分数对纤维动态力学性能有突出影响，特别是链段运动受其影响更为明显；HEMA质量分数对纤维表面和断面形貌均有显著影响，特别是当HEMA质量分数为15 wt%时，所得纤维表面出现了许多空洞，其断面存在许多尺寸不均的空洞。

A series of p-toluene sulfonylamido acetacylhydrazone derivatives were synthesized from p-toluenesulfonyl chloride which reacted with glycine to get the intermediate p-toluene sulfonylamido glycine, then through the esterification, hydrazinolysis to afford another intermediate p-toluene sulfonylamido acethydrazide, which condensed with different aldehydes to obtain the target compounds that were characterized by IR, 1H NMR, 13C NMR spectra and elemental analysis.

甲苯一硝化生成邻硝基甲苯、对硝基甲苯、间硝基甲苯，其中对硝基甲苯和间硝基甲苯的用量明显增加，提高它们在产物中比例的研究，具有十分可观的经济价值，所以本文从工业化的角度出发，通过改变温度和硝硫混酸的组成，分别对提高一硝基甲苯中对、间位异构体的比例进行研究。

In this paper, the chemical equilibrium constants of the reactions in the reaction system of toluene disproportionation and trimethylbenzene transalkylation reaction system were carefully calculated , and the equilibrium compositions of the components at different temperatures and different feed mole ratios were analysed .

对甲苯歧化与三甲苯烷基转移反应体系中反应的化学平衡常数进行了详细计算，并对不同温度、不同进料组成下的平衡组成进行了分析。结果表明，随温度升高，甲苯与三甲苯的芳烃平衡转化率降低，二甲苯的平衡组成亦降低；降低进料中甲苯和三甲苯的摩尔比，甲苯和三甲苯的总芳烃平衡转化率降低，而二甲苯的平衡组成明显上升。

The feedstock was changed from high purity meta- trimethylbenzene to meta- trimethylbenzene blended with 45%-55% mixed trimethylbenzene obtained from the top of the heavy component removal column; the original 3-column separation scheme was replaced by 2 columns; and modified the isomerization reaction system in compatible with the separation system for capacity enlarge.

金陵石化公司炼油厂针对异构化装置生产均三甲苯经济效益不明显的情况，改变了原料路线，在原以高纯度偏三甲苯为原料的基础上掺炼 4 5 %～ 5 5 %的脱重组分塔塔顶混合三甲苯；优化了均三甲苯分离流程，将原来的三塔流程改为两塔流程；进行了异构化反应系统与分离系统相匹配的扩容改造，收到了良好的效果，均三甲苯生产能力由 4 5 0t/a提高到 12 0 0t/a ，收率由 11%提高到 2 2 。0 %～ 2 4 。0 %，纯度由 97.9%提高到 98.9%。
