The nitrosamine concentration rises up to the equilibrium of the reaction of the stable nitrosamines in the solvent 1 (not evident in the diagram). The lower function shows a solvent 2 comprising the same secondary amine 4 and an additive 6 comprising a salt of vitamin C or E 3. The ...
The hydrodesulfurization process is one of the cornerstones of the chemical industry, removing harmful sulfur from oil to produce clean hydrocarbons. The reaction is catalyzed by the edges of MoS2 nanoislands and is operated in hydrogen-oil mixtures at 5
The S 2p3/2–S2 p1/2 spin-orbit splitting is measured for the free H2S molecule using both high-resolution x-ray photoelectron spectroscopy (XPS) and high-resolution photon-excited Auger-electron spectroscopy. It is found that the spin-orbit splitting differs in the two experiments by as much...
An experimental and modeling study of CO2 solubility in a 2-amino-2-methyl-1-propanol (AMP) + N-methyl-2-pyrrolidone (NMP) solution to gain an understanding of the effect of equilibrium time, temperature, CO2 loading, and amine concentration on the solubility of CO2 in solution. These......
