The adicity of methyl bonded to pyridine nucleus of the s-collidine depends on the solvent and the counterion nature. With Li+ or Na+ cations in Et2O, we have observed the decreasing acidity order: NH3 > Me-2 > o-tolunitrile > Me-4; with Li+ or Na+ in liquid NH3: o-tolunitrile > Me-4 > NH3 > Me-2. On the other hand, with K+ in Et2O or in liquid NH3: Me-4 Me-2 > NH3.
ME4-NH3 Ammonia Gas Sensor--Winsen. Winsen Electronics, as a professional gas sensor manufacturer, produce electrochemical ammonia sensor, NH3 sensor for industrial use, using electrochemical working principle. ME4-NH3 ammonia gas sensor is constant potential electrolysis type.
H3N2v is a non-human influenza virus that normally circulates in pigs and that has infected humans. Viruses that normally circulate in pigs are “ swine influenza viruses .”. When these viruses infect humans, they are termed “ variant ” viruses. In 2011, a specific H3N2 virus was detected with genes from avian, swine and human viruses ...
Jan 01, 1994· In [Zn(Me4 [l4]aneN4) (Cl)] [Cl04}, alternate folding about these axes causes an averaging of the NH2 and NH3 resonances in the fast exchange region. In the slow exchange region, folding about the diag- onal axes causes the NH2 and NH3 peaks to split into two resonances of equal areas, which gives a total of seven resonances.
