Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane. It is a colorless flammable liquid with an unpleasant smell. It is miscible with most organic solvents.
Isovaleraldehyde organic compound, also known as 3-methylbutanal, with the formula (CH 3) 2 CHCH 2 CHO. It is an aldehyde, a colorless liquid at STP, [1] and found in low concentrations in many types of food. [2] Commercially it is used as a reagent for the production of pharmaceuticals, perfumes and pesticides. [3]
Diacetyl (/ d aɪ j ə ˈ s iː t ə l / dy-yuh-SEE-tuhl; IUPAC systematic name: butanedione or butane-2,3-dione) is an organic compound with the chemical formula (CH 3 CO) 2. It is a yellow liquid with an intensely buttery flavor. It is a vicinal diketone (two C=O groups, side-by-side).
The living room had a mean of 18.1±17.5 μg m −3 and the bedroom was 18.2±16.9 μg m −3, whereas the outdoor air had a mean concentration of 2.3±2.6 μg m −3. [ citation needed ] It has been concluded that volatile organic compounds (VOC) such as benzene, formaldehyde, acetaldehyde, toluene, and xylenes have to be considered priority ...
Crotonaldehyde is produced by the aldol condensation of acetaldehyde: 2 CH 3 CHO → CH 3 CH=CHCHO + H 2 O. Crotonaldehyde is a multifunctional molecule that exhibits diverse reactivity. It is a prochiral dienophile. [5] It is a Michael acceptor. Addition of methylmagnesium chloride produces 3-penten-2-ol. [6]
CH 3 CH=CH 2 + H 2 O + 2 CO → CH 3 CH 2 CH 2 CH 2 OH + CO 2. In former times, butanol was prepared from crotonaldehyde, which can be obtained from acetaldehyde. Butanol can also be produced by fermentation of biomass by bacteria. Prior to the 1950s, Clostridium acetobutylicum was used in industrial fermentation to produce butanol. Research in ...
1,1-Diethoxyethane (acetaldehyde diethyl acetal) is a major flavoring component of distilled beverages, especially malt whisky [3] and sherry. [4] Although it is just one of many compounds containing an acetal functional group, this specific chemical is sometimes called simply acetal .
Pivaldehyde is an organic compound, more specifically an aldehyde.Shown in the image is a line-angle representation of this organic aldehyde, whose systematic name, 2,2-dimethylpropanal, is based on the longest carbon chain (three carbon atoms), ending in "-al" to indicate the aldehyde functionality, and where another descriptive synonym is trimethylacetaldehyde.
