WebNeutralization occurs as the base accepts hydrogen ions that the acid donates. These materials react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. They can initiate the polymerization of certain classes of organic compounds. WebWhen a plastic and a chemical are not compatible, the chemical essentially attacks the plastic in a reaction that causes the polymer structure to break down. This occurs at a molecular level and causes the chains that bind … WebTests of chemical reactors made of PA6-CF in the catalytic hydrogenation of alkynes showed the high efficiency of this material for the manufacturing of chemical equipment.
