The metal is either Sodium or a sodium - Potassium Alloy ( Na2K ). The molten metal is mixed with silica gel under constant agitation at Room Temperature . This phase 0 material must be handled in an inert atmosphere. Heating phase 0 at 150° C takes it to '''phase I'''. When this material is exposed to dry oxygen the reducing power is not affected. At further heating to 400° C '''phase II''' can be handled safely in an ambient environment. The metal reacts with the silicon gel in an Exothermic Reaction in which Na4Si4 Nanoparticles are formed. The powder reacts with water to form Hydrogen . Compounds such as Biphenyl and Naphthalene are reduced by the powder and form highly coloured Radical Anion s. The powder can also be introduced in a Column Chromatography setup and eluted with organic reactants in order to probe the reducing power. The powder is mixed with additional (wet) silica gel which provides additional hydrogen. A Birch Reduction of naphthalene takes 5 minutes elution time. The column converts benzyl chloride to bibenzyl in a Wurtz Coupling and in a similar fashion dibenzothiophene is reduced to Biphenyl . SEE ALSO REFERENCES |
