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).
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.
It is a precursor to many fine chemicals. A prominent industrial example is the crossed aldol condensation with diethyl ketone to give trimethylcyclohexenone, this can be easily converted to trimethylhydroquinone, which is a precursor to the vitamin E. [8] Other derivatives include crotonic acid, 3-methoxybutanol and the food preservative ...
Generic structure of acetals. In organic chemistry, an acetal is a functional group with the connectivity R 2 C(OR') 2. Here, the R groups can be organic fragments (a carbon atom, with arbitrary other atoms attached to that) or hydrogen, while the R' groups must be organic fragments not hydrogen. The two R' groups can be equivalent to each ...
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 .
The diketene acetal 3,9-diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane, DETOSU, is a reactive bifunctional monomer that forms biodegradable polyorthoesters by polyaddition with α,ω-diols. Polyorthoesters are used as embedding media for pharmaceuticals in extended release formulations for controlled drug release by surface erosion under ...
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 ...
Hydrogenation of 3-hydroxybutanal gives 1,3-butanediol: CH 3 CH(OH)CH 2 CHO + H 2 → CH 3 CH(OH)CH 2 CH 2 OH. This diol is a precursor to 1,3-butadiene, precursor to diverse polymers. Polymerization of 3-hydroxybutanal is also spontaneous, but can be stopped with the addition of water. Aldol has been used in making perfumes and in ore ...
