Butyraldehyde is produced almost exclusively by the hydroformylation of propylene: . CH 3 CH=CH 2 + H 2 + CO → CH 3 CH 2 CH 2 CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl but rhodium complexes are more common.
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.
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 a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− 1 / 3 ) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.
The sharing of an edge or a face of an octahedron gives a structure called bioctahedral. Many metal pentahalide and pentaalkoxide compounds exist in solution and the solid with bioctahedral structures. One example is niobium pentachloride. Metal tetrahalides often exist as polymers with edge-sharing octahedra. Zirconium tetrachloride is an ...
In organic chemistry, 3-hydroxybutanal (acetaldol, aldol) is an organic compound with the formula CH 3 CH(OH)CH 2 CHO and the structure H 3 C−CH−CH 2 −CH=O. It is classified as an aldol ( R−CH(OH)−CHR'−C(=O)−R" ) and the word "aldol" can refer specifically to 3-hydroxybutanal.
