Preparation A method for preparing N,N-dimethyl-p-phenylenediamine dihydrochloride includes the following steps: (1) Dissolve 1 mole of p-nitrochlorobenzene in 400 ml of toluene to obtain solution A; (2) Dissolve 1.1 moles of dimethylamine hydrochloride in 180 ml of water and add it to solutio...
1) Triamino substitution: Add the hydrocarbon solution of dimethylamine, the main raw material, to the reactor, and add the hydrocarbon solution of boron trichloride dropwise at -20℃to 0℃. After the drop is completed, the temperature of the system is raised to 5～25℃. Until the end of...
It is easily soluble in water with an intense yellow coloration and green fluorescence. 60 Acetic acid induces a change of the yellow coloration to a bright blue red. Mineral acids temporarily induce a red color, thereupon they separate a difficultly soluble blue compound, which can be converted...
, can result in the formation of a persistent foam on wastewater, which attenuates the exchange of gas and causes the water to stink [29]. Furthermore, high concentrations of AEOs in wastewater not only kill microorganisms and inhibit the degradation of other toxic substances, but also reduce ...
5.4-Phenoxypyridine method: DMAP is prepared by reacting 4-phenoxypyridine with dimethylamine at 200~210℃ in the presence of HBr. This method has difficult sources of raw materials, harsh reaction conditions, and is difficult to industrialize. The reaction formula is as follows: ...
In Escherichia coli, formation of new cells is mediated by the elongasome and divisome that govern cell elongation and septation, respectively. Proper transition between these events is essential to ensure viable progeny are produced; however, the compon
in which R and R1 each represent a hydrogen atom, or R-R1 represents the dimethylamine residue of a hexahydro-triazine ring, and in which R2 and R3 represent a hydrogen atom or a lower alkyl radical. The sulphonate may be N-acryloyl - N1 - sulphapropionyl - methylenedia mine, hexahydro...
