Propionaldehyde may also be prepared by oxidizing 1-propanol with a mixture of sulfuric acid and potassium dichromate.The reflux condenser contains water heated at 60 °C, which condenses unreacted propanol, but allows propionaldehyde to pass.
Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound.Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.
Industrial route to propionic anhydride involves thermal dehydration of propionic acid, driving off the water by distillation: . 2 CH 3 CH 2 CO 2 H → (CH 3 CH 2 CO) 2 O + H 2 O ...
1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH 3 CH 2 CH 2 OH and sometimes represented as PrOH or n-PrOH.It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.

In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
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.
It can also be prepared by combining ethylene, CO, and H 2. [4] When the reaction is catalyzed by dicobalt octacarbonyl, water can be used as a source of hydrogen.A proposed intermediate is the ethylene-propionyl species [CH 3 C(O)Co(CO) 3 (ethylene)] which undergoes a migratory insertion to form [CH 3 COCH 2 CH 2 Co(CO) 3].
