Ni compounds are excellent catalysts for the reduction of nitroaromatics and SiO_2 is a commonly-utilized catalyst for imine formation.

镍类催化剂是硝基还原的优秀催化剂，SiO_2是亚胺合成的常用促进剂，因而Ni/SiO_2很有可能是从芳香族硝基化合物和醛一锅合成亚胺的优良多功能催化剂。

However, for pentachlorophenol degradation, it is necessary to add over-dosage of oxidation reagent to mineralize PCP completely.

芬顿反应具有强氧化力，能对难分解有机物进行氧化作用，但若要对五氯酚(pentachlorophenol， PCP)这类含氯量甚高之芳香族化合物达成完全矿化分解，则需要添加大量的试剂，所费不赀，且对於污染场址现地施行时，其过程对环境冲击太大。

However, the synthetic potential of plant cells as a reducing agent of the nitro group has never been discovered, despite the fact that the reduction of nitro compounds is one of the most classical reactions in organic synthesis.

然而尽管硝基还原是最为经典之一的有机反应，在有机合成上还没有使用植物细胞还原芳香硝基化合物的报道。

The title compounds(B1-B6)were synthesized by the reaction of gastrodin's oxidate and aromatic amine .

目的：天麻苷(gastrodin，4-羟甲基苯基-β-D-吡喃葡萄糖苷)的氧化物，与芳香胺合成席夫碱化合物。

Weight loss: tea in caffeine, inositol, folic acid, pantothenic acid and aromatic substances and other compounds that can regulate fat metabolism, especially Oolong tea for protein and fat have a good decomposition.

6，体重下降：在咖啡因，肌醇，叶酸，泛酸和芳香物质和其他化合物，能调节脂肪代谢，特别是乌龙茶对蛋白质和脂肪的茶叶，茶叶有很好的分解。

Reductive dechlorination of polychlorinated biphenyls by zero-valent metal ;2. Zero-valent metals can be used to treat many kinds of pollutants including Organohalides,heavy metal,nitro-aromatic compounds,azo dye,perchloride and nitrate etc.

介绍了零价金属在处理环境污染物中的具体应用，包括卤代有机物、重金属、硝基芳香族化合物、偶氮染料、高氯酸盐以及硝酸盐等，指出零价金属可以通过还原和混凝吸附等作用有效地治理环境污染物，并分析了零价金属处理污染物的特点和应用前景。

This part introduce microporous zeolite compounds , especially the zeolite-like compounds which were developed by Yaghi et al by using thermally stable aromatic polyacid and metal ions as second building unit .

这部分介绍了微孔的类分子筛化合物，特别是 Yaghi 等利用刚性和热稳性本身比较好的芳香多酸和多碱配体和金属离子作为建筑单元发展的的第三代类分子筛，即：金属—有机框架。

The influence of the position of amino associated with pyrimidine on the reaction yields was discussed.

以取代的氨基嘧啶为共试剂，与多种芳香族硝基化合物进行了硒催化的羰基化反应，产率最高可达90％左右。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
