Daniel Berthelot: Part III. Contribution to photochemistry
Daniel Berthelot (1865-1927) used ultraviolet radiation from the mercury vapor lamp to carry out a series of oxidation and polymerization reactions, and proved that many reactions carried on by electrolysis could also be performed by photolysis. In doing so he discovered a myriad of unknown phenomena. By exposing to the action of UV a mixture of water and carbon dioxide, he achieved the synthesis of formic acid which then condensed and polymerized to produce vegetable sugars. A mixture of CO2 and NH3 gave rise to the simplest of the quaternary compounds, formamide, which represents the starting point for albuminous or proteinic substances, the basis of living matter.
