In this article, we explore, both theoretically and experimentally, the general reactivity of alkyl hydrogeno-phenylphosphinates with alcohols. We show that alcohol molecules act exclusively as nucleophilic species, and add to alkyl hydrogeno-phenylphosphinates, leading to pentacoordinated intermediates. These intermediates are …

Professional dry cell HHO generators vs wet cells. In a dry cell design only a minimum amount of liquid is contained in the generator body. Most of the water for the system is stored in a remote reservoir. Dry cells are much more efficient than wet cells as only insignificant amount of current gets wasted in electrolysis.

The most common chemical element in the universe is clean and readily available. Produced with renewable energies, green hydrogen is a potentially CO 2 -free raw material that is gaining global importance. Whether as raw material for the industry, as fuel for fuel cells or as a synthetic energy carrier – the possible applications are diverse.
Tu place ton aluminium dans une solution acide d'un sel de mercure et il se déposera du mercure sur l'aluminium. La présence du Mercure ne permet plus la formation de la couche protectrice d'alumine et l'action de l'eau libère alors de l'hydrogène. Ce genre de réaction fourni une boues d'hydroxyde gélatineuse qui ralenti l'action de l'eau ...
