Further hydrogenation does not take place until the amino group is cis and trans isomers is then oxidized by chromic acid in acetic acid to the ketone "'9 " '.

The zinc disc was then immersed in a bath of chromic acid; this etched a groove into the disc where the stylus had removed the coating, after which the recording could be played.
43.
While chromic acid baths are discouraged because of the high toxicity of chromium and the potential for explosions, aqua regia is itself very corrosive and has been implicated in several explosions due to mishandling.
44.
This latter name came from the practice of producing the chromic acid by adding sulphuric acid to potassium bichromate ( the old name for potassium dichromate ), even though the cell itself contained no bichromate.
45.
:Except for being highly toxic and a disposal issue ( i . e . you don't want it in the water supply ), chromic acid will clean the white off of rice.
46.
In 2006, Honeywell announced that its decision to stop manufacturing mercury switches had resulted in reductions of more than 11, 300 kg, 2800 kg, and 1500 kg respectively of mercury, lead, and chromic acid usage.
47.
He went to on complete his Doctor of Philosophy ( PhD ) there, writing his two-part 1943 thesis on " A kinetic study of the chromic acid oxidation of isopropyl alcohol " and " The iodination of fibroin ".
48.
Googling " cleaning glassware sulfuric acid nitric acid " gets me plenty of other textbooks suggesting the exact same formula, albeit as an alternative for the standard chromic acid . talk ) 16 : 50, 18 February 2013 ( UTC)

If the chromic acid oxidation is performed with stoichiometric oxidant in the presence of diethyl ether as co-solvent, a method introduced by H . C . Brown, the epimerization of l-menthone to d-isomenthone is largely avoided.
50.
In 1947, at the age of 36, he accepted the Sir Samuel Hall Chair of Chemistry at the University of Manchester After experimenting with different reagents, he discovered the Jones oxidation ( chromic acid oxidation of secondary alcohols to ketones in acetone ).
