Discovered ozone, worked on hydrogen peroxide, auto-oxidation, the passivity of iron, hydrosulfites, catalysts, and prussic acid. Professor of Chemistry at Basel from 1829 until the time of his death. He published more than 300 papers on chemical subjects. Reproduced from original in Kekule s portrait album. Figure 60.

The principle of the fuel cell was discovered by Christian Friedrich Schonbein (1799-1868)... [Pg.8]

The fuel cell concept has been known for more than 150 years. It was Christian Friedrich Schonbein who recognized and described the appearance of inverse electrolysis [4] shortly before Sir William Grove, the inventor of the platinum/ zinc battery, constructed his first gas voltaic battery [5]. Grove used platinum electrodes and dilute sulfuric acid as a proton conducting electrolyte. Sulfuric acid is still used today for the impregnation of porous separators serving as the electrolyte in direct methanol laboratory fuel cells [6], but the most commonly used fuel cell electrolytes today are hydrated acidic ionomers. As opposed to aqueous sulfuric acid, where the dissociated protons and the diverse sulfate anions (conjugated... [Pg.710]

Cellulose nitrate was first discovered in 1845 by the Swiss-German chemist Christian Friedrich Schonbein (1799-1868). The story is told that Schonbein used his wife s cotton apron to clean up some nitric acid that he had spilled on his laboratory floor. He was amazed to discover that the cotton and nitric acid reacted to form a new compound that exploded when heated, releasing a puff of black smoke. He immediately recognized the potential application for the new... [Pg.201]

Cellulose nitrate is produced in essentially the same way as it was (albeit accidentally) by Christian Schonbein in 1845. A mixture of nitric acid and sulfuric acid are added to cellulose in one of various forms (as wood pulp, powder, flakes, or a colloidal mixture with water, for example). The properties of the product formed depend on the relative quantities of each reagent used and the conditions under which the reaction is carried out. One of the most important variables is the amount... [Pg.203]
