A kinetic study of the mechanism of the nitrosation of dimethylamine ( DMA ) by propyl nitrite ( Pr ONO) in basic media to yield N-nitrosodimethylamine ( NDMA ) has found the rate equation to bewhere [ DMA ] and [ Pr ONO] are total concentrations. At 298.2 K and I =0.25 M , k ...
AtX NaDS=0.6, two monotonic curves can be distinguished in the ΔH (W→W+S)vs. m t trend. Experimental data were fitted through an equation previously reported for additives in pure surfactants derived by assuming the pseudo-phase transition model for the micellization and a mass action model...
The corresponding work of adhesion W was calculated using the DMT (Derjaguin, Muller, Toporov) equation. The values of W obtained are small compared to literature data and suggest that only a fraction of the functional groups in the contact area is involved in acid-base or H-bond ...
The latter finding strongly suggested that the solvent property of the micellar surface of nonionic DDAO is different from that of water and more like that of the Brij micelle surface. Thus the above equation is applicable to the micelle-solubilizate systems....
Of particular importance is the catalytic dehydrogenation of dimethylamine borane (Me2HN·BH3, DMAB), which can release hydrogen in the presence of suitable catalyst under mild conditions (Equation (1)) [6–10]. 2 2 (1) A number of catalysts have recently been employed in dehydrogenation of ...
The nN columns list the calculated increase in moles of N in the particles after exposure to NH3 or DMA calculated from the monitor data (Equation (3)) and AMS data (Equation (4)). The increase in N:C ratio 2 h after the injection of NH3 or DMA is reported as ∆N:C. Adding 2...
In order to confirm the desorption behavior of the two copolymer films, the recovery value (Re) was calculated using the following equation: 𝑅𝑒 (%)=𝑄𝑒(HCl)−𝑄𝑒(air)𝑄𝑒(HCl)×100Re %=QeHCl−QeairQeHCl×100 (2) where Qe(HCl) is the equilibrium binding capacity...
