二甲基苯胺

Many aromatic amine, such as aniline and N-methylaniline and diphenylamine, whose antidetonating quality are excellent, are not only often employed as concocting ingredient of antiknock but also suitable to research with electrochemical methods.

许多苯胺类化合物，如苯胺、N-甲基苯胺、二苯胺是性能良好的非金属抗爆制，也是抗爆剂常用的调合组分，且具有电子转移性质，适于电化学研究。

Saturated Ag/AgCl. Furthermore, in situ UV-Vis spectra showed that the electrocopolymerization between m-toluidine and p-phenylenediamine was performed. The p-phenylenediamine might react with m-toluidine to yield more active intermediates, which not only promote polymerization but also accelerate polymerization. In addition, through that p-phenylenediamine could be incorporated into copolymer to make the copolymer have a phenazine or phenazine like cyclic structure, which was proved by the FTIR of polymers.

在恒电位电解的条件下，相应的原位紫外-可见光谱和聚合物的傅立叶变换红外光谱表明间甲基苯胺和对苯二胺能发生电化学共聚反应，由于对苯二胺可能与间甲基苯胺形成了具有较强反应活性的中间体，使得对苯二胺的加入不但促进和加速了聚合反应，而且还结合进聚合物中形成了phenazine或类似于phenazine的环结构。

At first, Polyaniline was synthesized by the improved chemical oxidation technique, then, PANI/HCl, PANI/TSA and PANI/DBSA were obtained by doping emeraldine with HCl, 4-methyl benzene sulfonic acid and dodecylbenzene sulfonate acid, separately. Leucoemeraldine was obtained in the N-dimethylformamide by using phenylhydrazine deoxidizing emeraldine in N_2 atmosphere.

Versicolor suited to grow and produce laccases at pH value 3.5-5.7, and unbuffered media were able to get good laccase productivity though buffered media could get higher laccase activity. Metal ions Cu(superscript 2+) and Mn(superscript 2+) in the culture could remarkably increase the activity of laccases. The optimal concentration of Cu(superscript 2+) was 0.008-0.08mmol/L, and the optimal concentration of Mn(superscript 2+) was about 0.01mmol/L, when the culture contained 0.1mmol/L 2,5-dimethoxyaniline.

Methods: 2ethyl aniline was used as starting material of the synthesis and was processed by acetic anhydride acylation, strong nitric acid nitraction at low temperature, and desacyl synthesis to produce 2ethyl5nitro aniline. The product was then synthesized to 3methyl6nitro1Hindazole by using ringclosing reaction in the presence of NaNO2, and then ethylated to obtain 2,3diethyl6 nitro2Hindazole. The latter compound was then reduced by SnCl2/Hcl to get target compound 2,3diethyl6nitro2Hindazole.
