Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, ... When alcohol vapor makes contact with the orange dichromate-coated crystals, ...
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
The metabolization rate of related patients with kidney damage is abnormal in relation to percent in alcohol in the breath. However, since potassium dichromate is a strong oxidizer, numerous alcohol groups can be oxidized by kidney and blood filtration, producing false positives. [19]
For oxidations to the aldehydes and ketones, two equivalents of chromic acid oxidize three equivalents of the alcohol: 2 HCrO 4 − + 3 RR'C(OH)H + 8 H + + 4 H 2 O → 2 [Cr(H 2 O) 6] 3+ + 3 RR'CO. For oxidation of primary alcohols to carboxylic acids, 4 equivalents of chromic acid oxidize 3 equivalents of the alcohol. The aldehyde is an ...

Potassium permanganate: a strong oxidizing agent; can be used to quantitatively determine the total oxidisable organic material in an aqueous sample; a reagent for the synthesis of organic compounds Pyridinium chlorochromate: used to oxidize primary alcohols to aldehydes and secondary alcohols to ketones Pyridinium dichromate (Cornforth reagent)
If you are a heroin addict looking to get sober, Mike Greenwell, the center’s intake supervisor, is the first man you talk to. On a Saturday night in late March, Greenwell, 61, was still at his desk doing paperwork. He used to be a nightclub manager before alcohol and drug use got the better of him. He keeps a little radio tuned to classic rock.
Chrome alum. Chromium alum is produced from chromate salts or from ferrochromium alloys. Concentrated aqueous solutions of potassium dichromate can be reduced, usually with sulfur dioxide but also with alcohols or formaldehyde, in the presence of sulfuric acid at temperatures <40 °C.
