查询词典 amino-isovalerianic acid

A series of multi-pedal amino-compound with naphthol groups have been synthesized in this work. The photo-physical behaviors of these compounds in different solvents and different pH conditions have also been studied in details.

本工作合成了一系列带萘酚基的多足胺类化合物，对它们在不同溶剂及不同pH条件下的光物理行为进行了详细研究。

By using RT-PCR method, partial sequences of ppo genes were amplified from cDNA of Nelumbo nucifera's young leaves. After cloning and sequencing, 7 sequences ranging from 978bp to 1057bp were obtained, and they encoded 326 to 352 amino acids.

用RT-PCR方法，从中国莲幼叶RNA中成功扩增出ppo的部分序列，经克隆测序，得到长度在978~1057bP的序列共7个，编码326~352个氨基酸。

The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.

在邻位的位置引入立体阻碍大的溴原子，进而控制质子化过程的酸碱平衡只发生在 benzothiazole 上的氮原子上，企图达到只有中性分子，与单阳离子两种稳定的形式存在，经由外界的刺激下，例如温度或酸的量的改变，促使逆反应的发生，而达到热致变色的效果。

The experimental result is discussed in detail and it is proved that the nitro group in raw material cannot be reduced into amino group entirely.

在对实验结果作了详细的讨论后得出结论：在这一反应中，反应物中的硝基并没有被彻底还原为氨

With the occurrence of H2/Pd-C and ethyl formic ester,the reduction of the nitro group and the formylation of the amino group could be finished in one step.

但是在甲酸乙酯存在下，用H2/Pd-C对Ⅶ的硝基进行还原，得到的Ⅷ中的氨基可当即被甲酰化，使由Ⅶ到Ⅳ的两步反应一步完成。

The present work aims to investigate and develop a series of coumarin dyes containing nitro or amino benzimidazole group for the polyester and nylon fabrics and so on.

本实验主要目的乃针对聚酯、尼龙等织物制备出一系列含有硝基或胺基苯并咪唑基团之黄色萤光染料。

amino-1,4-naphthoquinones failed to be obtained through the classical routes due to the strongly electron-withdrawing nitro group, which deactivating the nucleophilic ability of the nitro anilines.

2-硝基苯胺-1，4-萘醌类衍生物由于硝基的强吸电性使硝基苯胺的亲核性减弱，不能通过经典的加成-氧化或加成-取代的方法合成得到。
