calculations predict that the catalytic effect of single ammonia and water molecule on OH + CH3OH reaction has no effect under tropospheric conditions because the dominated ammonia and water-assisted reaction depends on ammonia and water concentration, respectively. As a result, the total effective...

Therefore, because the pKa of water is lower than ammonia, it is a stronger acid the ammonia and will donate protons to the ammonia base. This reaction leads water to become the conjugate base OH- and ammonia to become the conjugate acid NH4+. Interestingly, this is why ammonia is a caus...

Reactions of zinc and cadmium atoms with ammonia molecules in a solid argon matrix have been studied by infrared spectroscopy. MNH 3 (M = Zn and Cd) was found from the reaction of ammonia with excited metal atoms, similar to the reaction... L Jiang,Q Xu - 《Bulletin of the Chemical So...
it is well known that CH2NH undergoes hydrolysis to yield ammonia and formaldehyde. The process of formation of ammonia and formaldehyde is acid-catalyzed and should be relatively rapid in aerosol droplets1,10,27. The interest of present work is to address the question of whether the gas phase...
