Sorry, no etymologies found.
By passage to a common osazone, he established the relation between glucose, fructose and mannose, which he discovered in 1888.
The reaction is assumed to be that of osazone formation.
After fermenting away the hexoses, the residue was treated with phenylhydrazine and an osazone separated.
By actual isolation of a crystalline dextrorotary sugar, by preparations of osazone and conversion into saccharic acid, it was proved that dextrose was the main product of hydrolysis.
The substance could not be identified as an osazone of any of the yet known pentoses.
There results, therefore, a dicarbonyl derivative ( 'osone'), which reacts directly with 2 mol. phenyl hydrazine in the cold to form an osazone.
From the products of decomposition the author obtained the osazone of hydroxypyruvic acid [Will, Ber.
